Do RC & UD sends behave the same on a mixed fabric?
What about MADs usen by the CM module?
And also who matches the different speeds of two different
hosts that are members of the same multicast group, as
there aren't any PathRecords in this case? For example if
a ddr host sends a datagram to a multicast group, does the
switch keep the incoming (fast) datagrams until the port
to the slow hosts is free?
