Michael -- I didn't notice before but you do seem to have misread the
ehca CQ polling code.  The ehca CQ poll operation doesn't actually
have the qp pointer readily available -- unless I'm mistaken, ehca
will have to do an expensive search by QPN in a hash table to get the
qp pointer.  That doesn't seem acceptable for every CQ poll, so do you
have any ideas of how to salvage this API change?
