[openib-general] [PATCH] enable IPoIB only if broadcast join finish

[Shirley Ma]

      Thanks Roland, I will apply the patch to the customer's cluster.

      The problem I found when failover bringing the new IPoIB interface up
in the existing fabric, with a limit number of multicast join groups from
our configuration, the interface can join broadcast group successfully, but
all hosts multicast group join failure. Then ib interface can be UP, but
not RUNNING. The interface couldn't work at all.

Thanks

I guess this is OK, but what is the urgent issue it fixes?
