According to user reports [1], the sae_password codepath doesn't actually work on machines with Cypress chips anyway, so no harm in removing it. This makes WPA3 work with iwd, or with wpa_supplicant pending a support patchset [2].

We recently talked about people testing brcmfmac patches, has anyone else tested this?Not sure I already replied so maybe I am repeating myself. I would prefer to keep the Cypress sae_password path as well although it reportedly does not work. The vendor support in the driver can be used to accommodate for that. The other option would be to have people with Cypress chipset test this patch. If that works for both we can consider dropping the sae_password path. Regards, ArendSo, if nobody from Cypress chimes in ever, and nobody cares nor tests Cypress chipsets, are we keeping any and all existing Cypress code-paths as bitrotting code forever and adding gratuitous conditionals every time any functionality needs to change "just in case it breaks Cypress" even though it has been tested compatible on Broadcom chipsets/firmware? Because that's not sustainable long term.
You should look into WEXT just for the fun of it. If it were up to me and a bunch of other people that would have been gone decades ago. Maybe a bad example if the sae_password is indeed not working, but the Cypress chipset is used in RPi3 and RPi4 so there must be a couple of users.
