mac80211: 802.11w - Optional software CCMP for management frames
If driver/firmware/hardware does not support CCMP for management
frames, it can now request mac80211 to take care of encrypting and
decrypting management frames (when MFP is enabled) in software. The
will need to add this new IEEE80211_KEY_FLAG_SW_MGMT flag when a CCMP
key is being configured for TX side and return the undecrypted frames
on RX side without RX_FLAG_DECRYPTED flag to use software CCMP for
management frames (but hardware for data frames).
