I would like to implement it simply by adding a new verb (kind of extended create_qp). I think this implementation will have similar characteristics with the XRC. Do you have any suggestions or preferences?

Hmm, I missed the original email.

Anyway I have no idea how to do the block multicast feature really.  I
thought there was some idea that userspace would pass QP creation flags
into the kernel?

Was there some reason that XRC wanted to use QP creation flags too?
