I think what we should do is follow the IB verbs extensions and expose
multiple CQ event vectors, and let the consumer pick which one to use
when creating a CQ. If IPoIB wants to go round robin itself, that
would be fine.
This is what I tried to set the userspace API up for. Nothing in
userspace would have to change for this -- the kernel just needs to
add multiple EQ support.
