/** \file
|
|
* An NVMf subsystem port, referred to as simply "port" is defined by the
|
|
* specification as follows:
|
|
*
|
|
* An NVM subsystem port (port) is a collection of one or more physical fabric
|
|
* interfaces that together act as a single interface between the NVM subsystem
|
|
* and a fabric. When link aggregation (e.g., Ethernet) is used, the physical
|
|
* ports for the group of aggregated links constitute a single NVM subsystem port.
