Thanks, applied with some fixes and cleanup. This broke hundreds of
hwsim test cases due to incorrect AP mode configuration and kernel
rejecting to start the AP because of that. I cleaned up the way the PSK
is set, or more importantly, not set in some cases.

What happens when this offload is used and a station request rekeying
with EAPOL-Key Request frame? Will the driver/firmware take care of
deriving a new PTK? What about GTK updates? Will those be handled in
driver/firmware as well? Would hostapd need some additional checks to
avoid periodic GTK rekeying or configuration that would result in trying
to do that?
