As an exmaple of vendor specific data we can extract rssi
and evm values for all the chains so one can see them on
per packet basis. More can be added depending on the needs i.e.
noise floor, Ness, STBC, key miss, etc.
AtheorsC OUI is used in this example but it should be replaced
by own when in use.
