Hello, It seems that in client mode, the Linux kernel only accepts an authentication frame after sending one itself. Is this interpretation correct? If that is the case, this would conflict with the SAE handshake as defined in the 802.11-2016 standard. That's because when the AP receives a Commit frame, the AP is allowed to send both a Commit and Confirm frame (see 12.4.8.6.3). So according to the standard, the client must accept a SAE Confirm authentication frame, even if it hasn't yet transmitted its own Confirm frame. So this appears to be a bug. Thoughts? Cheers, Mathy
