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.
