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.
