As a side note here on SAE, would you mind just doing 'iw list' and
seeing if SAE_OFFLOAD is listed in the extended feature list (for your
card). I also see 'sae' when I grep the FW, but its still not included
in ext features.

I have trying this on a Raspberry Pi, which is the brcmfac43455-
sdio.bin FW. I see you mentioned "cyfmac43455-sdio.bin", which I'm
guessing is a non-released version or something? I got my FW from an
official cypress release, Nov. 2020 I believe it was.

Thanks,
James
