The main change in most of the ACXs is the addition

for multi-role operation.

Currently, we don't really support multi-role, as

mac80211: Fill in skb->protocol information for injected frames

Some drivers (ath9k for example) are using skb->protocol to treat EAPOL
frames somehow special (disallow aggregation for example).

When running in AP mode hostapd injects the EAPOL frames through a
monitor interface and thus skb->protocol isn't set at all. Hence, if the
injected frame is a data frame and carries a rfc1042 headaer update the
skb->protocol field accordingly.

after issuing the connect command to the chip, the chip is sending
disconnect event and then immediately one connect event to the host
in some random cases.

cfg80211 SME state would have been in IDLE state, which was causing
the below kernel crash.

Now, host driver's sme state machine is checked every time before
delivering connect event to cfg80211
