Is the full document available as well?

SCSI targets are LLDs that sit below the mid-layer. iSCSI target on
the other hand is a "network" protocol driver, that sits above SCSI
(sd, st, sg, or directly over mid-layer). Seems like you'd need two
different frameworks, no?

To accomodate iSER, the iSCSI target driver itself would need to be
broken to the
iSCSI target engine, and the network (or data-mover aka DM) part. The
network part needs
an API that both the TCP DM and the ISER DM will provide. Does that make sense?
