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.
