Maybe not odd but counter-intuitive to some people. Anyway, I was 
looking at the code in driver_nl80211_capa.c and stumbled upon 
WPA_DRIVER_FLAGS_KEY_MGMT_OFFLOAD. I introduced entensible feature flags 
upstream just yesterday to accomodate this type of offload. Just curious 
but are those QCA vendor specific nl80211 commands used by the upstream 
QCA drivers or is this for supporting QCA proprietary drivers. I guess 
the latter as that would be the only reason I can think of to have 
vendor specific commands.
