Hauke Mehrtens a8f63a0717 mac80211: update to backports-4.14-rc2
This updates mac80211 to backprots-4.14-rc2.
This was compile and runtime tested with ath9k, ath10k and b43
with multiple stations and ieee80211w and in different scenarios by many
other people.

To create the backports-4.14-rc2-1.tar.xz use this repository:
https://git.kernel.org/pub/scm/linux/kernel/git/backports/backports.git
from tag v4.14-rc2-1

Then run this:
./gentree.py --git-revision v4.14-rc2 --clean  <path to linux repo> ../backports-4.14-rc2-1

This also adapts the ath10k-ct and mt76 driver to the changed cfg80211
APIs and syncs the nl80211.h file in iw with the new version from
backports-4.14-rc2.
