I have lots of testing facilities. :)

I mean, if no iWARP devices support these accelerated MPI collectives, then leave the rdmacm CPC in the openib btl so we can at least support iWARP via the openib BTL...

If you or someone can do the move and make it compile, I could then
test/debug/resolve all the other issues and make it work. I just balk
at the task of moving the stuff over because of my lack of knowledge of
the OMPI code above the openib/connect code.
