> [Impact]
> 
> AX211 might fail to load -64 firmware on some platforms.
> 
>   iwlwifi 0000:00:14.3: Failed to start RT ucode: -110
> 
> [Fix]
> 
> This can only be fixed in the firmware, and currently v5.14 kernel has
> FW API 64, v5.15 has 66 and only v5.16 or above has 67.
> 
> [Test Case]
> 
> Run checkbox reboot stress tests to try trigger this issue:
> 
>   $ checkbox-cli run com.canonical.certification::stress/reboot
> 
> [Where problems could occur]
> 
> The source commit originally contains 67 fw for several models, and
> yet AX211, which taks iwlwifi-so-a0-gf-a0-*.ucode and its
> corresponding pnvm file, is the only known problematic model
> affected. This pull request imports only the needed files to
> eliminate the possibility of regression as possible.
