Implement WPA3

[kallisti5]

wpa_supplicant 2.10 now supports wpa3 used for Wifi 6(e)

Here's a sample configuration from someone setting up wpa_supplicant for a Wifi 6:

pmf=2
sae_pwe=1
network={
   scan_ssid=1
   ssid=”Fill the Wi-Fi SSID here”
   key_mgmt=SAE
   proto=RSN
   ieee80211w=2
   sae_password=”Fill the Wi-Fi password here”
   pairwise=CCMP
   group=CCMP
}

Our network kit needs code additions to properly support WPA3

More information on WPA3: ​https://en.wikipedia.org/wiki/Wi-Fi_Protected_Access

Overview of changes:

• WPA3 uses SAE exchange instead of PSK exchange
• I think that's it? Still uses CCMP-128 from WPA2

This needs driver support, too. Until FreeBSD or OpenBSD makes the necessary modifications, it's pointless to change our own headers.

It does? Iirc only wpa_supplicant needs to be changed.

waddlesplash: what kind of driver support is needed?

as a side note: wpa_supplicant now also supports OWE

A lot of driver support is needed. The net80211 layer and also individual drivers need to handle different key types, flags, etc.

FreeBSD does seem to "support" the AX210, and even call it out as WIFI 6 / WIFI 6E ​https://wiki.freebsd.org/WiFi/Iwlwifi#Support-Matrix
