From 8b4509f642743e87f9a5c34bacb5d4b63ac730b4 Mon Sep 17 00:00:00 2001 From: Kevin Gan Date: Tue, 25 Sep 2012 20:23:45 -0700 Subject: [PATCH] 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.
