I would like to see only ULP timers defined in FCP-2.  All of the low level
Fibre Channel specific timers should be defined in the FC-PH/FC-AL
documents.  If you pull the low level timers out of the FC-PH/FC-AL
documents then it will become easier for someone developing the
hardware/firmware to overlook the requirements for these timer.  It also
becomes harder to follow the requirements for implementing Fibre Channel if
you separate these.

	Question 1)  Timers

	At present, the definitions of timers associated with various
	mechanisms are scattered across several documents, including FC-PLDA
	FC-TAPE and some of the FC-PH and FC-AL documents.  Should FCP-2
	over the specification of the timers on behalf of FC-PLDA and
	using only those defined by FC-PH without specification?

	If so, the stuff now in FC-TAPE, section 7 would be the basis for a
	corresponding new section in FCP-2.

	I feel that FCP-2 should take in these definitions, since it is
	in the recovery procedures.
