-/* XXX TODO:
- Someone should take packet-iscsi.c apart and break all the SCSI-CDB stuff
- out and put SCSI-CDB in packet-scsi.c instead.
- Then packet-iscsi.c only contains the iscsi layer and it will call
- packet-scsi.c to dissect the cdb's.
- Then we can call packet-scsi.c to dissect the scsi cdb's
- from here as well.
-
- volunteers?
