Re: iSCSI: Markers

[Matt Wakeley <matt_wakeley@agilent.com>]

I believe that the "initial marker-less interval" is unnecessary.  At
connection time, there are no "markers".  When both sides agree on markers,
they should also agree on when to start them.  The time might well be before
or after the default "initial marker-less interval" defined in the standard.
