		include frame delimiters (which mark frame boundaries and describe
		frame contents), primitive signals (indicate events), and primitive
		sequences (indicate or initiate port states).
		P
Participating mode		Mode in which an L_Port in a loop has valid AL_PA and can
		arbitrate, send frames, and retransmit received transmissions. See

Phantom	device	Device not physically in a loop but logically included by phantom
		address.
Phantom address		AL_PA value assigned to device not physically in loop. Also called

	PLOGI	Port Login. Port-to-port login process by which initiators establish
		sessions with targets. See also FLOGI.

		discovery.
	POST	Power On Self Test. Series of self-tests run after a switch is rebooted
		or reset.
Private	NL_Port	NL_Port that does not log into the fabric and communicates only
		with private NL_Ports in same loop.
Private device		Device that supports arbitrated loop protocol and understands 8-bit
		addresses, but cannot log into fabric.
Private loop		An arbitrated loop with no fibre channel attachment.
	Protocol	A defined method and standards for communication.
Public	NL_Port	NL_Port that logs into the fabric, can function within public or
		private loops, and can communicate with public or private NL_Ports.
Public device		Device that supports arbitrated loop protocol, understands 8-bit
		addresses, and can log into fabric.
Public loop		An arbitrated loop attached to a switch.
