Just need some clarification on this: 

We use the o2ib driver for Lustre IB communication. We also use IPoIB to define IP addresses for the IB interfaces in the network. Does the MTU configuration parameter impact Lustre in any way? My understanding is that LNET is only using IPoIB for address resolution when using o2ib.
