Intel AX210 does not report RX bitrate for 'ax' standard

[Tonny_]

Hi,

I'm facing an issue on Ubuntu 22.04 linux where there is no information reported about RX bitrate when iw dev [interface] link command is invoked during operating in 'ax' standard - HE mode.

Instead of phy rate, MCS, NSS etc. only bandwidth is reported preceded by "(unknown)" comment. 

For 'ac' standard - VHT - every single parameter is reported as expected for both TX / RX. 

It was checked on couple of AP's with the same result.

logs:

iw link command result for 'ax' standard:
