the following patchlines in the v3 patch look wrong

enctype));


the enctype != wpa2 isnt enough since it also belongs to ccmp-256,
gcmp modes etc.
4.14 doesn't support CCMP-256 nor GCMP modes yet. Did you check the
separate patch for 4.15:

for me ccmp-256 and gcmp works but my current tree is based on a very recent mac80211 version

but did not check if this support is included in 4.14 since i'm developing embedded wireless firmwares on different kernel versions using wireless backports based on recent mac80211 /ath10k etc. versions
