Our initiator is implemented as a lower layer adapter driver and therefore
also interfaces with the mid-level.

I'd be very interested in seeing your target work, ours is just getting
under way.  Our implementation hasn't been tested yet since we don't have
a target.

Sounds just about where we are at.  The only v5 stuff I've added has been
changing the opcode values.
