If I'm understanding you correctly, the target software assigns one
scsi_host to only one remote initiator.  This would mean that you want to
assign an entire physical adapter on the target side to a tgt scsi_host
that an initiator will see?  And then this would be a 1:1 relationship
of initiator to target.  Is this all correct?
