Subject: mwifiex: 11h handling for AP interface
X-Git-Tag: fixes-v4.0-rc1~150^2~10^2~67
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cf075eac9ca94ec54b5ae0c0ec798839f962be55;p=pandora-kernel.git

mwifiex: 11h handling for AP interface

This patch enables 11h extensions in FW upon detecting DFS
channel in start radar detection/channel switch handlers.
Patch also takes care of disabling 11h when non DFS channels
are to be set during start_ap handler.
