rS308823: [net80211] handle hardware encryption offload in the receive path
Summary
  • teach the crypto modules about receive offload - although I have to do some further reviewing in places where we /can't/ have an RX key
  • teach the RX data path about receive offload encryption - check the flag, handle NULL key, do decap and checking as appropriate.

Sure, but if we get a hardware key but it strips the IV, we still can't really check anything. :(
