I have no experience in doing multirail on ethernet, sorry. The 
principle is exactly the same as for Infiniband, but as Infiniband 
interfaces cannot be bonded (except for IPoIB which is not of interest 
when considering performance), I cannot tell.

Adding a second NID only serves for high-availability purpose when 
establishing the initial connection.
