Merge tag 'mac80211-for-davem-2015-12-02' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211
Johannes Berg says:
====================
A small set of fixes for 4.4:
* fix scanning in mac80211 to not actively scan radar
channels (from Antonio)
* fix uninitialized variable in remain-on-channel that
could lead to treating frame TX as remain-on-channel
and not sending the frame at all
* remove NL80211_FEATURE_FULL_AP_CLIENT_STATE again, it
was broken and needs more work, we'll enable it later
* fix call_rcu() induced use-after-reset/free in mesh
(that was suddenly causing issues in certain tests)
* always request block-ack window size 64 as we found
some APs will otherwise crash (really ...)
* fix P2P-Device teardown sequence to avoid restarting
with uninitialized data
====================
