Subject: [Bluetooth] Always include MTU in L2CAP config responses
X-Git-Tag: v2.6.19~56^2~8
X-Git-Url: http://www.pilppa.org/gitweb/gitweb.cgi?a=commitdiff_plain;h=820ae1b865caa05e0614004d0183ca70de2b8665;p=linux-2.6-omap-h63xx.git

[Bluetooth] Always include MTU in L2CAP config responses

When sending a positive config response it shall include the actual
MTU to be used on this channel. This differs from the Bluetooth 1.1
specification where it was enough to acknowledge the config request.
