52 * A queued port is a port that has an infinite queue for outgoing
53 * packets and thus decouples the module that wants to send
54 * request/responses from the flow control (retry mechanism) of the
55 * port. A queued port can be used by both a master and a slave. The
56 * queue is a parameter to allow tailoring of the queue implementation
57 * (used in the cache).
