Rx ports use packet queues referred to as “receive queues” to forward completed received packets to the host or another peer port entity. Rx ports may be configured in various ways to forward the received packets onto any number of receive queues. Rx ports may choose to queue their receive packets based strictly on Rx channel, protocol type, priority, direct forwarding requirements (i.e. to another ports Tx queue) or any combination of these and this is application specific. In many cases the receive queue is in fact also a transmit queue for another peer entity. It is just a matter of semantics with respect to which port is referenced in the system.
