[ofa-general] Re: [openib-general] Fw: [PATCH] enable IPoIB only if broadcast join finish

[Shirley Ma]

Jason,

      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.

Thanks
Shirley Ma
