Reserved bits. Write as 0.
The default priority of a frame received on port 1, 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.
If set, the priority information found within the MAC address table is used.
Enable IP priority resolution for frame received on port n.
If set, the IP DiffServ/COS field is used and priority is resolved according to the IP_PRIORITYn setting for
the port.
If cleared, IP Diffserv/COS fields are ignored.
Enable VLAN priority resolution for frame received on port n.
