Ok, it seems that the iscsitgtd from b91 doesn't support RESERVE(6) but
the latest does. However, in addition to the RESERVE(6) from AIX,
there's also a RESERVE(10) (opcode 0x56). According to lba_table in
usr/src/cmd/iscsi/iscsitgtd/t10_sbc.c, there is no support for this. Any
plans to add RESERVE(10) and RELEASE(10) support?
