It doesn't work for the reason I mentioned below -- the driver says that
the firmware included in the driver does not support multiple ports.
("non-MULTIID f/w loaded")

I did a quick experiment, and commented out the check, and was apparently
able to enable multiple ports in CTL.  CTL just saw more target-capable
ports.

But my FreeBSD initiator had some definite problems connecting to the target
with multiple ports enabled.
