From: Duane Grigsby <duane.grigsby@xxxxxxxxxx>
This code provides the interfaces to register remote and local ports
of FC4 type 0x28 with the FC-NVMe transport and transports the
requests (FC-NVMe FC link services and FC-NVMe commands IUs) to the
fabric. It also provides the support for allocating h/w queues and
aborting FC-NVMe FC requests.
