From f21243a82253e34f64187aeb3d7f93fb7cb92536 Mon Sep 17 00:00:00 2001 From: Thomas Pedersen Date: Fri, 27 Jul 2012 18:13:27 -0700 Subject: ath6kl: reconfigure RSN capabilities when restarting AP If the firmware decides to initiate a channel switch on an AP vif running an RSN BSS, reconfigure the saved RSN IE capabilities as well. Fixes a bug where the beacon and 4-way handshake would have a capability mismatch after a channel switch, since the firmware apparently clears these on an AP disconnect.
