Depends on the 4-tuple.  The demux done in the TOE hw uses  src 
addr/port and dst addr/port.  So since the rNFS connection will always 
have the reserved rNFS port for the server side, the 4-tuple will always 
be unique.  The netperf traffic would go up the NIC side and the rNFS 
traffic up the TOE side...
