[ofa-general] opensm: bad multicast forwarding table entries

[akepner at sgi.com]

FWIW, I asked for the additional data that Hal requested. 

But this time there are no occurrences of "Disconnected 
switch|HCA" errors from 'ibdiagnet -r'. 

The entire cluster was recently rebooted (probably the IB 
switches, too), opensm restarted, etc. So that seems to have 
cleared things up, at least for now.

But this is something that we've seen on quite a few occasions, 
so we'll keep looking for it, and grab what debug info we can 
when it crops up again.
