I did not get any output with multicast_debug_level! But I added some more
debugging and finally realized that the set was not being sent. :-( I put a
debug statement in OpenSM where the flag was set and therefore thought that
OpenSM had set the rereg bit. However, since no other data had changed the
"set" MAD was not sent. (I am getting a bit tongue tied reading this back. I
hope that all makes sense.)
Here is a patch which fixes the problem. (At least with the partial sub-nets
configuration I explained before.) I will have to verify this fixes the problem
I originally reported.
