Check if wifi6e 6GHz band enabled with Kernel less then 5.15 or Ubuntu older then 20.xx

[Sylvain Pineau (sylvain-pineau)]

The way you're parsing iw output should be added to the existing https://git.launchpad.net/plainbox-provider-resource/tree/jobs/resource.pxu#n268 resource job wireless_sta_protocol (Station supported protocols as opposed to AP mode).

I've already added some logic to guess from iw output if ax is supported via MCS 0-11.

I think you can add a new property to this resource to add info about the 6GHz support
