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
====================
