From: Kevin Gan Date: Wed, 26 Sep 2012 03:23:45 +0000 (-0700) Subject: mwifiex: add inactivity deauth support for ap X-Git-Tag: firefly_0821_release~3680^2~1949^2~30^2~19 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=8b4509f642743e87f9a5c34bacb5d4b63ac730b4;p=firefly-linux-kernel-4.4.55.git mwifiex: add inactivity deauth support for ap The firmware has support for this feature, so we offload it to firmware. In start_ap, driver passes the inactivity timeout value to firmware via TLVs and firmware will report STA_DEAUTH event to driver when inactivity timer is fired.
