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
