		FC Remote Ports (rports)
		========================
		<< To Be Supplied >>

		In the Fibre Channel (FC) subsystem, a remote port (rport) refers to a
		remote Fibre Channel node that the local port can communicate with.
		These are typically storage targets (e.g., arrays, tapes) that respond
		to SCSI commands over FC transport.

		In Linux, rports are managed by the FC transport class and are
		represented in sysfs under:

		/sys/class/fc_remote_ports/

		Each rport directory contains attributes describing the remote port,
		such as port ID, node name, port state, and link speed.

		rports are typically created by the FC transport when a new device is
		discovered during a fabric login or scan, and they persist until the
		device is removed or the link is lost.

		Common attributes:
		- node_name: World Wide Node Name (WWNN).
		- port_name: World Wide Port Name (WWPN).
		- port_id: FC address of the remote port.
		- roles: Indicates if the port is an initiator, target, or both.
		- port_state: Shows the current operational state.

		After discovering a remote port, the driver typically populates a
		fc_rport_identifiers structure and invokes fc_remote_port_add() to
		create and register the remote port with the SCSI subsystem via the
		Fibre Channel (FC) transport class.

		rports are also visible via sysfs as children of the FC host adapter.

		For developers: use fc_remote_port_add() and fc_remote_port_delete() when
		implementing a driver that interacts with the FC transport class.
