Thanks for the clarification, Roland, I see that the previous
discussion had successfully confused me. So is it the case that the
create and the joins to a multicast group have to specify the correct
speed? And the problem then would be that a IB host at boot doesn't
know the right speed? Am I getting colder or warmer?
