mac80211: ath10k: allow failure getting board id via otp ath10k tries to fetch board id via otp, but that fails for many chips like QCA988x, QCA9984 etc. Recent commit cc189c0b7f removed the earlier hack that had allowed QCA radios to work, as that hack was incompatible with the new wifi chips being introduced to the source tree. Restore functionality for the existing wifi chips by modifying the return value of the 'board id via otp' function to a value that is recognised as a harmless error, so that name evaluation continues by using the board file. Patch originally suggested by Christian Lamparter in forum discussion. Signed-off-by: Hannu Nyman <hannu.nyman@iki.fi>

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.
