Trying to sum up what has been shared (a few weeks ago) in both the
linux-wireless kernel mailing-list and the hostapd mailing-list, a way
to find Linux drivers with support for 802.11w / PMF / MFP (required
for WPA3), including both mac80211-based drivers and cfg80211-based,
aka fullmac, drivers, is:

https://elixir.bootlin.com/linux/latest/ident/MFP_CAPABLE
https://elixir.bootlin.com/linux/latest/ident/WLAN_CIPHER_SUITE_AES_CMAC
