iSCSI: WN Field (draft -04)

[Steve Senum <ssenum@cisco.com>]

Julian:

Some questions on the WN field in draft -04. wrt. the bits
used to encode the digest types on the header and/or
data segment:

1. Why are these needed since the use of the digests
is negotiated?

2. What should they be set to if one of the Kerberos
digests are used?  When a proprietary digest is used?

Perhaps they could be changed to two one bit fields
to indicate whether the digest is simply present or not.

Also, I would also suggest inverting the meaning of the
next header type bit (bit 7).

Regards,
Steve Senum
