[resending with correct netdev address, not sure how that ended up in
my autocompletion address book ... sorry about that!]

Hi Dave,

Sorry for being so late. These have been pending for a while (and in
fact in linux-next too, I asked to be added there recently :) ).

Let me know if there's any problem.

Thanks,
johannes

  mac80211: don't teardown sdata on sdata stop (2015-11-20 11:40:50
+0100)

----------------------------------------------------------------
A small set of fixes for 4.4:
 * remove NL80211_FEATURE_FULL_AP_CLIENT_STATE again, it
   was broken and needs more work, we'll enable it for 4.5
 * 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

I've got two more fairly important changes - one for regulatory issues
and one for an uninitialized variable that was leading to fairly
obscure bugs - do you prefer I wait, or send a new pull request
covering this one plus the two new fixes?

Thanks,
johannes

Please add them and send a new pull request, I'll just skip over your
existing one.

THanks.

Ok, here we go, below a new pull request.

I've added the two commits I spoke about, fixing scanning and an
uninitialized cookie variable that lead to problems if the value
happened to be 0.

Let me know if there's any problem!

Thanks,
johannes

  mac80211: fix off-channel mgmt-tx uninitialized variable usage (2015-12-02 22:27:53 +0100)

----------------------------------------------------------------
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 ...)
