I was under th= e impression brcmfmac doesn't support it. Anyways, I've asked a fedora user to compile a kernel with CONFIG_BRCMDBG.

Tested by a user on bcm4364b2 wifi chip with > a WPA2-PSK [AES] network. dmesg output: 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
