According to Larry [1] (and successfully verified on b43) mac80211 transparently falls back to software for unsupported hardware cyphers. Thus, there's no reason for not unconditionally enabling MFP. This gives us WPA3 support out of the box, without having to manually disable hardware crypto. Tested on an RT2790-based Wi-Fi card.
