iSCSI: Rejecting immediate commands

["Ayman Ghanem" <aghanem@cisco.com>]

Julian,

In draft-09 section 2.2.2.1, 6th paragraph:

        "..........................  Immediate commands can be rejected by
        the iSCSI target due to lack of resources. An iSCSI target MUST be
        able to handle at least one immediate task management command and
one
        immediate non-task-management iSCSI request per connection at any
        time."

If the target MUST handle two immediate commands per connection, and with
number of connections possibly negotiated to a large value
<number-from-1-to-65535>, this can add up to significant resources the
session has to have.

Since the command sequence numbering is session wide, I would think the
limit should be per session, not per connection.
