Hi all,

I have been trying to use NetworkManager together with cypress-fmac-v5.4.18-2021_0527 patches on mainline 5.4.18 kernel. Currently nearly all is working correctly except few issues, which were fixed together with little help from Beniamino Galvani of NM RedHat Team. My issue is in here Hotspot WPA3 support - this is the second half of the issue, because first one was solved with upgrading NM from 1.32 branch to 1.33. In brief, together with Beniamino we have discovered, that the driver is not returning RSN_AUTH_KEY_MGMT_SAE. We suspect that the problem is that the SAE AKM is not set in the NL80211_ATTR_AKM_SUITES netlink attribute by the driver. I have used grep to find it and i did not find any. My question is it possible that all suits are defined in the firmware and is it possible that this specific suite is missing? Is it possible for the cypress team to solve this issue because it is needed by the NM to set a wpa3 hotspot.

@Dvergatal , sorry for the delay in response, WPA3 support is chip dependent, Could you please let us know which module you are using? 

Could you please let us know if you were able to patch the file "0012-nl80211-Support-SAE-authentication-offload-in-AP-mod.patch" ? 

Also could you please verify if CONFIG_SAE=y in the kernel config file.

@Vivek_gunapati hi n/p.

The model i have is AMPAK AP6356S on firefly-rk3399 board. I was able to patch with this file and i have also CONFIG_SAE=y in the kernel config file. As we were talking on this thread, the driver is returning me that the device is supporting SAE with AUTHENTICATE command. Also connection as client to WPA3 network is working.
