Unfortunately the external auth support is not yet implemented in IWD. The brcmfmac driver itself is rather unique being a fullmac driver. Depending on how you look at it, this on its own is "easier" to support. It handles connecting/roaming all on its own. But then, for some reason, someone didn't want to do SAE/WPA3 on the card itself so they came up with some one-off mechanism to offload that onto userspace. This is one of those things that got put upstream that is a pain for projects like IWD to support IMO. Its something we do need to support eventually, especially given the raspi 5 requires it.
