OK - I'll start applying these now.  Expect check-ins before the end of
the day.

We haven't touched performance yet.  We'll be looking at that real soon.
That said, 26Mb/sec is slower than we see.  We'll get back to you after
we investigate this a bit.

Huh.  That should work.  I'll look at it.

>  - ibv_ud_pingpong on loopback doesn't work either:

Ditto.

Great.  Thanks.

I'll think up a better name.  libipath is already taken with something
else we ship, so I can't use that.
