[ofa-general] Setting lowest-common denominator ipoib multicast rate?

[Troy Benjegerdes]

How can I set the ipoib broadcast multicast group rate such that even a 
1X SDR connected machine can still join the group?

I tried the following in /etc/osm-partitions.conf based on a mail list 
posting from awhile ago, but it doesn't seem to work..

Default=0x7fff,ipoib,rate=1:ALL=full;



And then what does it take on the ipoib client side to pick up the new 
partition parameters and such? reloading ipoib, or a full restart?
