The whole purpose of this patch is trying to address network accessbility when MLIDs have limitation in the fabrics. We have a customer hit this problem in a large cluster. Basically the IPv4 doesn't work at all (since the interface can't up and running becacuse of IPv6 soliciated nodes address IB mulitcast join failure) when MLIDs exceeds a certain number because of the switch limitation with IPv6 module preloaded.<br>
