this though and the recommendation to allow only a single
interface in STA mode at first!

+What: old static regulatory information and ieee80211_regdom module parameter
+When: 2.6.29
+Why: The old regulatory infrastructure has been replaced with a new one
+ which does not require statically defined regulatory domains. We do
+ not want to keep static regulatory domains in the kernel due to the
+ the dynamic nature of regulatory law and localization. We kept around
+ the old static definitions for the regulatory domains of:
+ * US
+ * JP
+ * EU
+ and used by default the US when CONFIG_WIRELESS_OLD_REGULATORY was
+ set. We also kept around the ieee80211_regdom module parameter in case
+ some applications were relying on it. Changing regulatory domains
+ can now be done instead by using nl80211, as is done with iw.

+ 6.4 The virtual CAN driver (vcan)
+
+ Similar to the network loopback devices, vcan offers a virtual local
+ CAN interface. A full qualified address on CAN consists of
+
+ - a unique CAN Identifier (CAN ID)
+ - the CAN bus this CAN ID is transmitted on (e.g. can0)
+
+ so in common use cases more than one virtual CAN interface is needed.
+
+ The virtual CAN interfaces allow the transmission and reception of CAN
+ frames without real CAN controller hardware. Virtual CAN network
+ devices are usually named 'vcanX', like vcan0 vcan1 vcan2 ...
+ When compiled as a module the virtual CAN driver module is called vcan.ko
+
+ Since Linux Kernel version 2.6.24 the vcan driver supports the Kernel
+ netlink interface to create vcan network devices. The creation and
+ removal of vcan network devices can be managed with the ip(8) tool:
+
+ - Create a virtual CAN network interface:
+ ip link add type vcan
+
+ - Create a virtual CAN network interface with a specific name 'vcan42':
+ ip link add dev vcan42 type vcan
+
+ - Remove a (virtual CAN) network interface 'vcan42':
+ ip link del vcan42
+
+ The tool 'vcan' from the SocketCAN SVN repository on BerliOS is obsolete.
+
+ Virtual CAN network device creation in older Kernels:
+ In Linux Kernel versions < 2.6.24 the vcan driver creates 4 vcan
+ netdevices at module load time by default. This value can be changed
+ with the module parameter 'numdev'. E.g. 'modprobe vcan numdev=8'

+Section 2: Qdisc support for multiqueue devices
+
+-----------------------------------------------
+
+Currently two qdiscs are optimized for multiqueue devices. The first is the
+default pfifo_fast qdisc. This qdisc supports one qdisc per hardware queue.
+A new round-robin qdisc, sch_multiq also supports multiple hardware queues. The
+qdisc is responsible for classifying the skb's and then directing the skb's to
+bands and queues based on the value in skb->queue_mapping. Use this field in
+the base driver to determine which queue to send the skb to.
+
+sch_multiq has been added for hardware that wishes to avoid head-of-line
+blocking. It will cycle though the bands and verify that the hardware queue
+associated with the band is not stopped prior to dequeuing a packet.
+
+On qdisc load, the number of bands is based on the number of queues on the
+hardware. Once the association is made, any skb with skb->queue_mapping set,
+will be queued to the band associated with the hardware queue.
+
+
+Section 3: Brief howto using MULTIQ for multiqueue devices
+---------------------------------------------------------------
+
+The userspace command 'tc,' part of the iproute2 package, is used to configure
+qdiscs. To add the MULTIQ qdisc to your network device, assuming the device
+is called eth0, run the following command:
+
+# tc qdisc add dev eth0 root handle 1: multiq
+
+The qdisc will allocate the number of bands to equal the number of queues that
+the device reports, and bring the qdisc online. Assuming eth0 has 4 Tx
+queues, the band mapping would look like:
+
+band 0 => queue 0
+band 1 => queue 1
+band 2 => queue 2
+band 3 => queue 3
+
+Traffic will begin flowing through each queue based on either the simple_tx_hash
+function or based on netdev->select_queue() if you have it defined.
+
+The behavior of tc filters remains the same. However a new tc action,
+skbedit, has been added. Assuming you wanted to route all traffic to a
+specific host, for example 192.168.0.3, through a specific queue you could use
+this action and establish a filter such as:
+
+tc filter add dev eth0 parent 1: protocol ip prio 1 u32 \
+ match ip dst 192.168.0.3 \
+ action skbedit queue_mapping 3

+Linux Phonet protocol family
+============================
+
+Introduction
+------------
+
+Phonet is a packet protocol used by Nokia cellular modems for both IPC
+and RPC. With the Linux Phonet socket family, Linux host processes can
+receive and send messages from/to the modem, or any other external
+device attached to the modem. The modem takes care of routing.
+
+Phonet packets can be exchanged through various hardware connections
+depending on the device, such as:
+ - USB with the CDC Phonet interface,
+ - infrared,
+ - Bluetooth,
+ - an RS232 serial port (with a dedicated "FBUS" line discipline),
+ - the SSI bus with some TI OMAP processors.
+
+
+Packets format
+--------------
+
+Phonet packets have a common header as follows:
+
+ struct phonethdr {
+ uint8_t pn_media; /* Media type (link-layer identifier) */
+ uint8_t pn_rdev; /* Receiver device ID */
+ uint8_t pn_sdev; /* Sender device ID */
+ uint8_t pn_res; /* Resource ID or function */
+ uint16_t pn_length; /* Big-endian message byte length (minus 6) */
+ uint8_t pn_robj; /* Receiver object ID */
+ uint8_t pn_sobj; /* Sender object ID */
+ };
+
+On Linux, the link-layer header includes the pn_media byte (see below).
+The next 7 bytes are part of the network-layer header.
+
+The device ID is split: the 6 higher-order bits consitute the device
+address, while the 2 lower-order bits are used for multiplexing, as are
+the 8-bit object identifiers. As such, Phonet can be considered as a
+network layer with 6 bits of address space and 10 bits for transport
+protocol (much like port numbers in IP world).
+
+The modem always has address number zero. All other device have a their
+own 6-bit address.
+
+
+Link layer
+----------
+
+Phonet links are always point-to-point links. The link layer header
+consists of a single Phonet media type byte. It uniquely identifies the
+link through which the packet is transmitted, from the modem's
+perspective. Each Phonet network device shall prepend and set the media
+type byte as appropriate. For convenience, a common phonet_header_ops
+link-layer header operations structure is provided. It sets the
+media type according to the network device hardware address.
+
+Linux Phonet network interfaces support a dedicated link layer packets
+type (ETH_P_PHONET) which is out of the Ethernet type range. They can
+only send and receive Phonet packets.
+
+The virtual TUN tunnel device driver can also be used for Phonet. This
+requires IFF_TUN mode, _without_ the IFF_NO_PI flag. In this case,
+there is no link-layer header, so there is no Phonet media type byte.
+
+Note that Phonet interfaces are not allowed to re-order packets, so
+only the (default) Linux FIFO qdisc should be used with them.
+
+
+Network layer
+-------------
+
+The Phonet socket address family maps the Phonet packet header:
+
+ struct sockaddr_pn {
+ sa_family_t spn_family; /* AF_PHONET */
+ uint8_t spn_obj; /* Object ID */
+ uint8_t spn_dev; /* Device ID */
+ uint8_t spn_resource; /* Resource or function */
+ uint8_t spn_zero[...]; /* Padding */
+ };
+
+The resource field is only used when sending and receiving;
+It is ignored by bind() and getsockname().
+
+
+Low-level datagram protocol
+---------------------------
+
+Applications can send Phonet messages using the Phonet datagram socket
+protocol from the PF_PHONET family. Each socket is bound to one of the
+2^10 object IDs available, and can send and receive packets with any
+other peer.
+
+ struct sockaddr_pn addr = { .spn_family = AF_PHONET, };
+ ssize_t len;
+ socklen_t addrlen = sizeof(addr);
+ int fd;
+
+ fd = socket(PF_PHONET, SOCK_DGRAM, 0);
+ bind(fd, (struct sockaddr *)&addr, sizeof(addr));
+ /* ... */
+
+ sendto(fd, msg, msglen, 0, (struct sockaddr *)&addr, sizeof(addr));
+ len = recvfrom(fd, buf, sizeof(buf), 0,
+ (struct sockaddr *)&addr, &addrlen);
+
+This protocol follows the SOCK_DGRAM connection-less semantics.
+However, connect() and getpeername() are not supported, as they did
+not seem useful with Phonet usages (could be added easily).
+
+
+Phonet Pipe protocol
+--------------------
+
+The Phonet Pipe protocol is a simple sequenced packets protocol
+with end-to-end congestion control. It uses the passive listening
+socket paradigm. The listening socket is bound to an unique free object
+ID. Each listening socket can handle up to 255 simultaneous
+connections, one per accept()'d socket.
+
+ int lfd, cfd;
+
+ lfd = socket(PF_PHONET, SOCK_SEQPACKET, PN_PROTO_PIPE);
+ listen (lfd, INT_MAX);
+
+ /* ... */
+ cfd = accept(lfd, NULL, NULL);
+ for (;;)
+ {
+ char buf[...];
+ ssize_t len = read(cfd, buf, sizeof(buf));
+
+ /* ... */
+
+ write(cfd, msg, msglen);
+ }
+
+Connections are established between two endpoints by a "third party"
+application. This means that both endpoints are passive; so connect()
+is not possible.
+
+WARNING:
+When polling a connected pipe socket for writability, there is an
+intrinsic race condition whereby writability might be lost between the
+polling and the writing system calls. In this case, the socket will
+block until write because possible again, unless non-blocking mode
+becomes enabled.
+
+
+The pipe protocol provides two socket options at the SOL_PNPIPE level:
+
+ PNPIPE_ENCAP accepts one integer value (int) of:
+
+ PNPIPE_ENCAP_NONE: The socket operates normally (default).
+
+ PNPIPE_ENCAP_IP: The socket is used as a backend for a virtual IP
+ interface. This requires CAP_NET_ADMIN capability. GPRS data
+ support on Nokia modems can use this. Note that the socket cannot
+ be reliably poll()'d or read() from while in this mode.
+
+ PNPIPE_IFINDEX is a read-only integer value. It contains the
+ interface index of the network interface created by PNPIPE_ENCAP,
+ or zero if encapsulation is off.

+Linux wireless regulatory documentation
+---------------------------------------
+
+This document gives a brief review over how the Linux wireless
+regulatory infrastructure works.
+
+More up to date information can be obtained at the project's web page:
+
+http://wireless.kernel.org/en/developers/Regulatory
+
+Keeping regulatory domains in userspace
+---------------------------------------
+
+Due to the dynamic nature of regulatory domains we keep them
+in userspace and provide a framework for userspace to upload
+to the kernel one regulatory domain to be used as the central
+core regulatory domain all wireless devices should adhere to.
+
+How to get regulatory domains to the kernel
+-------------------------------------------
+
+Userspace gets a regulatory domain in the kernel by having
+a userspace agent build it and send it via nl80211. Only
+expected regulatory domains will be respected by the kernel.
+
+A currently available userspace agent which can accomplish this
+is CRDA - central regulatory domain agent. Its documented here:
+
+http://wireless.kernel.org/en/developers/Regulatory/CRDA
+
+Essentially the kernel will send a udev event when it knows
+it needs a new regulatory domain. A udev rule can be put in place
+to trigger crda to send the respective regulatory domain for a
+specific ISO/IEC 3166 alpha2.
+
+Below is an example udev rule which can be used:
+
+# Example file, should be put in /etc/udev/rules.d/regulatory.rules
+KERNEL=="regulatory*", ACTION=="change", SUBSYSTEM=="platform", RUN+="/sbin/crda"
+
+The alpha2 is passed as an environment variable under the variable COUNTRY.
+
+Who asks for regulatory domains?
+--------------------------------
+
+* Users
+
+Users can use iw:
+
+http://wireless.kernel.org/en/users/Documentation/iw
+
+An example:
+
+ # set regulatory domain to "Costa Rica"
+ iw reg set CR
+
+This will request the kernel to set the regulatory domain to
+the specificied alpha2. The kernel in turn will then ask userspace
+to provide a regulatory domain for the alpha2 specified by the user
+by sending a uevent.
+
+* Wireless subsystems for Country Information elements
+
+The kernel will send a uevent to inform userspace a new
+regulatory domain is required. More on this to be added
+as its integration is added.
+
+* Drivers
+
+If drivers determine they need a specific regulatory domain
+set they can inform the wireless core using regulatory_hint().
+They have two options -- they either provide an alpha2 so that
+crda can provide back a regulatory domain for that country or
+they can build their own regulatory domain based on internal
+custom knowledge so the wireless core can respect it.
+
+*Most* drivers will rely on the first mechanism of providing a
+regulatory hint with an alpha2. For these drivers there is an additional
+check that can be used to ensure compliance based on custom EEPROM
+regulatory data. This additional check can be used by drivers by
+registering on its struct wiphy a reg_notifier() callback. This notifier
+is called when the core's regulatory domain has been changed. The driver
+can use this to review the changes made and also review who made them
+(driver, user, country IE) and determine what to allow based on its
+internal EEPROM data. Devices drivers wishing to be capable of world
+roaming should use this callback. More on world roaming will be
+added to this document when its support is enabled.
+
+Device drivers who provide their own built regulatory domain
+do not need a callback as the channels registered by them are
+the only ones that will be allowed and therefore *additional*
+cannels cannot be enabled.
+
+Example code - drivers hinting an alpha2:
+------------------------------------------
+
+This example comes from the zd1211rw device driver. You can start
+by having a mapping of your device's EEPROM country/regulatory
+domain value to to a specific alpha2 as follows:
+
+static struct zd_reg_alpha2_map reg_alpha2_map[] = {
+ { ZD_REGDOMAIN_FCC, "US" },
+ { ZD_REGDOMAIN_IC, "CA" },
+ { ZD_REGDOMAIN_ETSI, "DE" }, /* Generic ETSI, use most restrictive */
+ { ZD_REGDOMAIN_JAPAN, "JP" },
+ { ZD_REGDOMAIN_JAPAN_ADD, "JP" },
+ { ZD_REGDOMAIN_SPAIN, "ES" },
+ { ZD_REGDOMAIN_FRANCE, "FR" },
+
+Then you can define a routine to map your read EEPROM value to an alpha2,
+as follows:
+
+static int zd_reg2alpha2(u8 regdomain, char *alpha2)
+{
+ unsigned int i;
+ struct zd_reg_alpha2_map *reg_map;
+ for (i = 0; i < ARRAY_SIZE(reg_alpha2_map); i++) {
+ reg_map = ®_alpha2_map[i];
+ if (regdomain == reg_map->reg) {
+ alpha2[0] = reg_map->alpha2[0];
+ alpha2[1] = reg_map->alpha2[1];
+ return 0;
+ }
+ }
+ return 1;
+}
+
+Lastly, you can then hint to the core of your discovered alpha2, if a match
+was found. You need to do this after you have registered your wiphy. You
+are expected to do this during initialization.
+
+ r = zd_reg2alpha2(mac->regdomain, alpha2);
+ if (!r)
+ regulatory_hint(hw->wiphy, alpha2, NULL);
+
+Example code - drivers providing a built in regulatory domain:
+--------------------------------------------------------------
+
+If you have regulatory information you can obtain from your
+driver and you *need* to use this we let you build a regulatory domain
+structure and pass it to the wireless core. To do this you should
+kmalloc() a structure big enough to hold your regulatory domain
+structure and you should then fill it with your data. Finally you simply
+call regulatory_hint() with the regulatory domain structure in it.
+
+Bellow is a simple example, with a regulatory domain cached using the stack.
+Your implementation may vary (read EEPROM cache instead, for example).
+
+Example cache of some regulatory domain
+
+struct ieee80211_regdomain mydriver_jp_regdom = {
+ .n_reg_rules = 3,
+ .alpha2 = "JP",
+ //.alpha2 = "99", /* If I have no alpha2 to map it to */
+ .reg_rules = {
+ /* IEEE 802.11b/g, channels 1..14 */
+ REG_RULE(2412-20, 2484+20, 40, 6, 20, 0),
+ /* IEEE 802.11a, channels 34..48 */
+ REG_RULE(5170-20, 5240+20, 40, 6, 20,
+ NL80211_RRF_PASSIVE_SCAN),
+ /* IEEE 802.11a, channels 52..64 */
+ REG_RULE(5260-20, 5320+20, 40, 6, 20,
+ NL80211_RRF_NO_IBSS |
+ NL80211_RRF_DFS),
+ }
+};
+
+Then in some part of your code after your wiphy has been registered:
+
+ int r;
+ struct ieee80211_regdomain *rd;
+ int size_of_regd;
+ int num_rules = mydriver_jp_regdom.n_reg_rules;
+ unsigned int i;
+
+ size_of_regd = sizeof(struct ieee80211_regdomain) +
+ (num_rules * sizeof(struct ieee80211_reg_rule));
+
+ rd = kzalloc(size_of_regd, GFP_KERNEL);
+ if (!rd)
+ return -ENOMEM;
+
+ memcpy(rd, &mydriver_jp_regdom, sizeof(struct ieee80211_regdomain));
+
+ for (i=0; i < num_rules; i++) {
+ memcpy(&rd->reg_rules[i], &mydriver_jp_regdom.reg_rules[i],
+ sizeof(struct ieee80211_reg_rule));
+ }
+ r = regulatory_hint(hw->wiphy, NULL, rd);
+ if (r) {
+ kfree(rd);
+ return r;
+ }
+

+Transparent proxy support
+=========================
+
+This feature adds Linux 2.2-like transparent proxy support to current kernels.
+To use it, enable NETFILTER_TPROXY, the socket match and the TPROXY target in
+your kernel config. You will need policy routing too, so be sure to enable that
+as well.
+
+
+1. Making non-local sockets work
+================================
+
+The idea is that you identify packets with destination address matching a local
+socket on your box, set the packet mark to a certain value, and then match on that
+value using policy routing to have those packets delivered locally:
+
+# iptables -t mangle -N DIVERT
+# iptables -t mangle -A PREROUTING -p tcp -m socket -j DIVERT
+# iptables -t mangle -A DIVERT -j MARK --set-mark 1
+# iptables -t mangle -A DIVERT -j ACCEPT
+
+# ip rule add fwmark 1 lookup 100
+# ip route add local 0.0.0.0/0 dev lo table 100
+
+Because of certain restrictions in the IPv4 routing output code you'll have to
+modify your application to allow it to send datagrams _from_ non-local IP
+addresses. All you have to do is enable the (SOL_IP, IP_TRANSPARENT) socket
+option before calling bind:
+
+fd = socket(AF_INET, SOCK_STREAM, 0);
+/* - 8< -*/
+int value = 1;
+setsockopt(fd, SOL_IP, IP_TRANSPARENT, &value, sizeof(value));
+/* - 8< -*/
+name.sin_family = AF_INET;
+name.sin_port = htons(0xCAFE);
+name.sin_addr.s_addr = htonl(0xDEADBEEF);
+bind(fd, &name, sizeof(name));
+
+A trivial patch for netcat is available here:
+http://people.netfilter.org/hidden/tproxy/netcat-ip_transparent-support.patch
+
+
+2. Redirecting traffic
+======================
+
+Transparent proxying often involves "intercepting" traffic on a router. This is
+usually done with the iptables REDIRECT target; however, there are serious
+limitations of that method. One of the major issues is that it actually
+modifies the packets to change the destination address -- which might not be
+acceptable in certain situations. (Think of proxying UDP for example: you won't
+be able to find out the original destination address. Even in case of TCP
+getting the original destination address is racy.)
+
+The 'TPROXY' target provides similar functionality without relying on NAT. Simply
+add rules like this to the iptables ruleset above:
+
+# iptables -t mangle -A PREROUTING -p tcp --dport 80 -j TPROXY \
+ --tproxy-mark 0x1/0x1 --on-port 50080
+
+Note that for this to work you'll have to modify the proxy to enable (SOL_IP,
+IP_TRANSPARENT) for the listening socket.
+
+
+3. Iptables extensions
+======================
+
+To use tproxy you'll need to have the 'socket' and 'TPROXY' modules
+compiled for iptables. A patched version of iptables is available
+here: http://git.balabit.hu/?p=bazsi/iptables-tproxy.git
+
+
+4. Application support
+======================
+
+4.1. Squid
+----------
+
+Squid 3.HEAD has support built-in. To use it, pass
+'--enable-linux-netfilter' to configure and set the 'tproxy' option on
+the HTTP listener you redirect traffic to with the TPROXY iptables
+target.
+
+For more information please consult the following page on the Squid
+wiki: http://wiki.squid-cache.org/Features/Tproxy4
3.1 Guidelines for wireless device drivers
------------------------------------------
+(in this text, rfkill->foo means the foo field of struct rfkill).
+
1. Each independent transmitter in a wireless device (usually there is only one
transmitter per device) should have a SINGLE rfkill class attached to it.
when possible) the overall transmitter rfkill state, not of a particular rfkill
line.
-5. During suspend, the rfkill class will attempt to soft-block the radio
-through a call to rfkill->toggle_radio, and will try to restore its previous
-state during resume. After a rfkill class is suspended, it will *not* call
-rfkill->toggle_radio until it is resumed.
+5. The wireless device driver MUST NOT leave the transmitter enabled during
+suspend and hibernation unless:
+
+ 5.1. The transmitter has to be enabled for some sort of functionality
+ like wake-on-wireless-packet or autonomous packed forwarding in a mesh
+ network, and that functionality is enabled for this suspend/hibernation
+ cycle.
+
+AND
+
+ 5.2. The device was not on a user-requested BLOCKED state before
+ the suspend (i.e. the driver must NOT unblock a device, not even
+ to support wake-on-wireless-packet or remain in the mesh).
+
+In other words, there is absolutely no allowed scenario where a driver can
+automatically take action to unblock a rfkill controller (obviously, this deals
+with scenarios where soft-blocking or both soft and hard blocking is happening.
+Scenarios where hardware rfkill lines are the only ones blocking the
+transmitter are outside of this rule, since the wireless device driver does not
+control its input hardware rfkill lines in the first place).
+
+6. During resume, rfkill will try to restore its previous state.
+
+7. After a rfkill class is suspended, it will *not* call rfkill->toggle_radio
+until it is resumed.
+

-/**
- * ath5k_hw_set_bssid_mask - set common bits we should listen to
- *
- * The bssid_mask is a utility used by AR5212 hardware to inform the hardware
- * which bits of the interface's MAC address should be looked at when trying
- * to decide which packets to ACK. In station mode every bit matters. In AP
- * mode with a single BSS every bit matters as well. In AP mode with
- * multiple BSSes not every bit matters.
- *
- * @ah: the &struct ath5k_hw
- * @mask: the bssid_mask, a u8 array of size ETH_ALEN
- *
- * Note that this is a simple filter and *does* not filter out all
- * relevant frames. Some non-relevant frames will get through, probability
- * jocks are welcomed to compute.
- *
- * When handling multiple BSSes (or VAPs) you can get the BSSID mask by
- * computing the set of:
- *
- * ~ ( MAC XOR BSSID )
- *
- * When you do this you are essentially computing the common bits. Later it
- * is assumed the harware will "and" (&) the BSSID mask with the MAC address
- * to obtain the relevant bits which should match on the destination frame.
- *
- * Simple example: on your card you have have two BSSes you have created with
- * BSSID-01 and BSSID-02. Lets assume BSSID-01 will not use the MAC address.
- * There is another BSSID-03 but you are not part of it. For simplicity's sake,
- * assuming only 4 bits for a mac address and for BSSIDs you can then have:
- *
- * \
- * MAC: 0001 |
- * BSSID-01: 0100 | --> Belongs to us
- * BSSID-02: 1001 |
- * /
- * -------------------
- * BSSID-03: 0110 | --> External
- * -------------------
- *
- * Our bssid_mask would then be:
- *
- * On loop iteration for BSSID-01:
- * ~(0001 ^ 0100) -> ~(0101)
- * -> 1010
- * bssid_mask = 1010
- *
- * On loop iteration for BSSID-02:
- * bssid_mask &= ~(0001 ^ 1001)
- * bssid_mask = (1010) & ~(0001 ^ 1001)
- * bssid_mask = (1010) & ~(1001)
- * bssid_mask = (1010) & (0110)
- * bssid_mask = 0010
- *
- * A bssid_mask of 0010 means "only pay attention to the second least
- * significant bit". This is because its the only bit common
- * amongst the MAC and all BSSIDs we support. To findout what the real
- * common bit is we can simply "&" the bssid_mask now with any BSSID we have
- * or our MAC address (we assume the hardware uses the MAC address).
- *
- * Now, suppose there's an incoming frame for BSSID-03:
- *
- * IFRAME-01: 0110
- *
- * An easy eye-inspeciton of this already should tell you that this frame
- * will not pass our check. This is beacuse the bssid_mask tells the
- * hardware to only look at the second least significant bit and the
- * common bit amongst the MAC and BSSIDs is 0, this frame has the 2nd LSB
- * as 1, which does not match 0.
- *
- * So with IFRAME-01 we *assume* the hardware will do:
- *
- * allow = (IFRAME-01 & bssid_mask) == (bssid_mask & MAC) ? 1 : 0;
- * --> allow = (0110 & 0010) == (0010 & 0001) ? 1 : 0;
- * --> allow = (0010) == 0000 ? 1 : 0;
- * --> allow = 0
- *
- * Lets now test a frame that should work:
- *
- * IFRAME-02: 0001 (we should allow)
- *
- * allow = (0001 & 1010) == 1010
- *
- * allow = (IFRAME-02 & bssid_mask) == (bssid_mask & MAC) ? 1 : 0;
- * --> allow = (0001 & 0010) == (0010 & 0001) ? 1 :0;
- * --> allow = (0010) == (0010)
- * --> allow = 1
- *
- * Other examples:
- *
- * IFRAME-03: 0100 --> allowed
- * IFRAME-04: 1001 --> allowed
- * IFRAME-05: 1101 --> allowed but its not for us!!!

+ *
+ * @ah: the &struct ath5k_hw
+ * @mask: the bssid_mask, a u8 array of size ETH_ALEN
+ *
+ * BSSID masking is a method used by AR5212 and newer hardware to inform PCU
+ * which bits of the interface's MAC address should be looked at when trying
+ * to decide which packets to ACK. In station mode and AP mode with a single
+ * BSS every bit matters since we lock to only one BSS. In AP mode with
+ * multiple BSSes (virtual interfaces) not every bit matters because hw must
+ * accept frames for all BSSes and so we tweak some bits of our mac address
+ * in order to have multiple BSSes.
+ *
+ * NOTE: This is a simple filter and does *not* filter out all
+ * relevant frames. Some frames that are not for us might get ACKed from us
+ * by PCU because they just match the mask.
+ *
+ * When handling multiple BSSes you can get the BSSID mask by computing the
+ * set of ~ ( MAC XOR BSSID ) for all bssids we handle.
+ *
+ * When you do this you are essentially computing the common bits of all your
+ * BSSes. Later it is assumed the harware will "and" (&) the BSSID mask with
+ * the MAC address to obtain the relevant bits and compare the result with
+ * (frame's BSSID & mask) to see if they match.
+ */
+/*
+ * Simple example: on your card you have have two BSSes you have created with
+ * BSSID-01 and BSSID-02. Lets assume BSSID-01 will not use the MAC address.
+ * There is another BSSID-03 but you are not part of it. For simplicity's sake,
+ * assuming only 4 bits for a mac address and for BSSIDs you can then have:
+ *
+ * \
+ * MAC: 0001 |
+ * BSSID-01: 0100 | --> Belongs to us
+ * BSSID-02: 1001 |
+ * /
+ * -------------------
+ * BSSID-03: 0110 | --> External
+ * -------------------
+ *
+ * Our bssid_mask would then be:
+ *
+ * On loop iteration for BSSID-01:
+ * ~(0001 ^ 0100) -> ~(0101)
+ * -> 1010
+ * bssid_mask = 1010
+ *
+ * On loop iteration for BSSID-02:
+ * bssid_mask &= ~(0001 ^ 1001)
+ * bssid_mask = (1010) & ~(0001 ^ 1001)
+ * bssid_mask = (1010) & ~(1001)
+ * bssid_mask = (1010) & (0110)
+ * bssid_mask = 0010
+ *
+ * A bssid_mask of 0010 means "only pay attention to the second least
+ * significant bit". This is because its the only bit common
+ * amongst the MAC and all BSSIDs we support. To findout what the real
+ * common bit is we can simply "&" the bssid_mask now with any BSSID we have
+ * or our MAC address (we assume the hardware uses the MAC address).
+ *
+ * Now, suppose there's an incoming frame for BSSID-03:
+ *
+ * IFRAME-01: 0110
+ *
+ * An easy eye-inspeciton of this already should tell you that this frame
+ * will not pass our check. This is beacuse the bssid_mask tells the
+ * hardware to only look at the second least significant bit and the
+ * common bit amongst the MAC and BSSIDs is 0, this frame has the 2nd LSB
+ * as 1, which does not match 0.
+ *
+ * So with IFRAME-01 we *assume* the hardware will do:
+ *
+ * allow = (IFRAME-01 & bssid_mask) == (bssid_mask & MAC) ? 1 : 0;
+ * --> allow = (0110 & 0010) == (0010 & 0001) ? 1 : 0;
+ * --> allow = (0010) == 0000 ? 1 : 0;
+ * --> allow = 0
+ *
+ * Lets now test a frame that should work:
+ *
+ * IFRAME-02: 0001 (we should allow)
+ *
+ * allow = (0001 & 1010) == 1010
+ *
+ * allow = (IFRAME-02 & bssid_mask) == (bssid_mask & MAC) ? 1 : 0;
+ * --> allow = (0001 & 0010) == (0010 & 0001) ? 1 :0;
+ * --> allow = (0010) == (0010)
+ * --> allow = 1
+ *
+ * Other examples:
+ *
+ * IFRAME-03: 0100 --> allowed
+ * IFRAME-04: 1001 --> allowed
+ * IFRAME-05: 1101 --> allowed but its not for us!!!

+ The Phone Network protocol (PhoNet) is a packet-oriented
+ communication protocol developped by Nokia for use with its modems.
+
+ This is required for Maemo to use cellular data connectivity (if
+ supported). It can also be used to control Nokia phones
+ from a Linux computer, although AT commands may be easier to use.
+
+ To compile this driver as a module, choose M here: the module
+ will be called phonet. If unsure, say N.

+config WIRELESS_OLD_REGULATORY
+ bool "Old wireless static regulatory definitions"
+ default n
+ ---help---
+ This option enables the old static regulatory information
+ and uses it within the new framework. This is available
+ temporarily as an option to help prevent immediate issues
+ due to the switch to the new regulatory framework which
+ does require a new userspace application which has the
+ database of regulatory information (CRDA) and another for
+ setting regulatory domains (iw).
+
+ For more information see:
+
+ http://wireless.kernel.org/en/developers/Regulatory/CRDA
+ http://wireless.kernel.org/en/users/Documentation/iw
+
+ It is important to note though that if you *do* have CRDA present
+ and if this option is enabled CRDA *will* be called to update the
+ regulatory domain (for US and JP only). Support for letting the user
+ set the regulatory domain through iw is also supported. This option
+ mainly exists to leave around for a kernel release some old static
+ regulatory domains that were defined and to keep around the old
+ ieee80211_regdom module parameter. This is being phased out and you
+ should stop using them ASAP.
+
+ Say N unless you cannot install a new userspace application
+ or have one currently depending on the ieee80211_regdom module
+ parameter and cannot port it to use the new userspace interfaces.
+
+ This is scheduled for removal for 2.6.29.

- * This regulatory domain control implementation is highly incomplete, it
- * only exists for the purpose of not regressing mac80211.
- *
- * For now, drivers can restrict the set of allowed channels by either
- * not registering those channels or setting the IEEE80211_CHAN_DISABLED
- * flag; that flag will only be *set* by this code, never *cleared.
+/**
+ * DOC: Wireless regulatory infrastructure
*
* The usual implementation is for a driver to read a device EEPROM to
* determine which regulatory domain it should be operating under, then
* looking up the allowable channels in a driver-local table and finally
* registering those channels in the wiphy structure.
*
- * Alternatively, drivers that trust the regulatory domain control here
- * will register a complete set of capabilities and the control code
- * will restrict the set by setting the IEEE80211_CHAN_* flags.
+ * Another set of compliance enforcement is for drivers to use their
+ * own compliance limits which can be stored on the EEPROM. The host
+ * driver or firmware may ensure these are used.
+ *
+ * In addition to all this we provide an extra layer of regulatory
+ * conformance. For drivers which do not have any regulatory
+ * information CRDA provides the complete regulatory solution.
+ * For others it provides a community effort on further restrictions
+ * to enhance compliance.
+ *
+ * Note: When number of rules --> infinity we will not be able to
+ * index on alpha2 any more, instead we'll probably have to
+ * rely on some SHA1 checksum of the regdomain for example.
