This conflicts with Bart's patches to improve failover; it will be much
better to use his approach to block the target rather than remove it
wholesale -- we could have lost connectivity as a transient and may get
it back quickly if someone grabbed the wrong cable, etc.

Also, we should only kill the one target on DREQ, and we already have a
pointer to it from the CM context -- no need to search.

It is a good idea to hook into the event mechanism; this is something
I've long wanted to incorporate (as Vu did in OFED). I'm looking at
getting Bart's series to a point I can merge it, and I'll pull in your
ideas -- with credit -- there.

Thanks,
