On bcm4377, bcm4378 and bcm4388 (chipsets used in M1/M2 macs)
WPA3-SAE and WPA2-PSK still works with Fedora's wpa_supplicant 2.10.
Fedora's package carried SAE offload patches in 2.10.
wpa_supplicant 2.11 still doesn't work with this patch but it prevents a
kernel oops after a disconnect (due to an authentication timeout in the
current broken state) in wpa_supplicant.

I'll continue to debug the wpa_supplicant 2.11

best regards,
Janne
