I think the driver should always set it. If the driver doesn't set it, it will be seen as invalid by the MAC layer.

If the radio doesn't support CRC calculation, this should be ignored via radio_caps (see #11473 ). If the driver doesn't provide a flag for the CRC (but does the calculations), it can be set to valid anyway.
