Yes, I agree.  Domain (target, topology, etc) discovery should be
"part" of the transport class.

What I'm thinking of is that the LLDD would register a known
trasport class with the SCSI Core at/after registering a host
template and then would call something with a name like
"start_scsi" which would do whatever necessary for the domain
(SAS, FC, iSCSI, etc) before scanning for targets.  Of course
for some domains no additional work is needed.
