Currently, FCoE has multiple Rx queues available, along with a redirection table, that helps distribute the I/O load across multiple CPUs based on the FC exchange ID. To make this the most effective, we need to provide the same layout of transmit queues to match receive. Particularly, when Data Center Bridging (DCB) is enabled, the designated traffic class for FCoE can have dedicated queues for just FCoE traffic, while not affecting any other type of traffic flow.
