iSCSI: C bit in Login Request?

["KRUEGER,MARJORIE (HP-Roseville,ex1)" <marjorie_krueger@hp.com>]

Julian,
I don't understand the need for the C bit in the Login Request?  The target
certainly knows whether this is the first request in a login sequence
without this bit, and I wouldn't trust an initiator to set it correctly
anyway, so I'd double check it with my knowledge of the # of PDUs received
on this connection (or #bytes received).
