If set, the VLAN tag field of a frame is inspected and priority is resolved according to the setting programmed
in VLAN_PRIORITYn for the port on which the frame was received.
If cleared, VLAN priority is ignored.
Reserved bits. Write as 0.
The default priority of a frame received on port 2, if none of the priority resolutions could define a priority of
the frame. Up to 3 bits can be implemented.
Reserved bits. Write as 0.
Enable MAC based priority resolution for frame received on port n.
