+ Classification Rule=>
+ Multicast: (*addr1 & 0x01) == 0x01
+ Specific : bDHCPFrame, bARPFrame, bEAPOLFrame, etc.
+ 11N Rate : If peer support HT
+ (1).AMPDU -- If TXBA is negotiated.
+ (2).AMSDU -- If AMSDU is capable for both peer and ourself.
+ *). AMSDU can embedded in a AMPDU, but now we didn't support it.
+ (3).Normal -- Other packets which send as 11n rate.
+
+ B/G Rate : If peer is b/g only.
+ (1).ARALINK-- If both of peer/us supprot Ralink proprietary Aggregation and the TxRate is large than RATE_6
+ (2).Normal -- Other packets which send as b/g rate.
+ Fragment:
+ The packet must be unicast, NOT A-RALINK, NOT A-MSDU, NOT 11n, then can consider about fragment.
+
+ Classified Packet Handle Rule=>
+ Multicast:
+ No ACK, //pTxBlk->bAckRequired = FALSE;
+ No WMM, //pTxBlk->bWMM = FALSE;
+ No piggyback, //pTxBlk->bPiggyBack = FALSE;
+ Force LowRate, //pTxBlk->bForceLowRate = TRUE;
+ Specific : Basically, for specific packet, we should handle it specifically, but now all specific packets are use
+ the same policy to handle it.
+ Force LowRate, //pTxBlk->bForceLowRate = TRUE;
+
+ 11N Rate :
+ No piggyback, //pTxBlk->bPiggyBack = FALSE;
+
+ (1).AMSDU
+ pTxBlk->bWMM = TRUE;
