Detailed Description

A structure used to configure the VMDQ+DCB feature of an Ethernet port.

Using this feature, packets are routed to a pool of queues, based on the vlan id in the vlan tag, and then to a specific queue within that pool, using the user priority vlan tag field.

A default pool may be used, if desired, to route all traffic which does not match the vlan filter rules.
