You have mentioned the listeners, but what about the ports
used for the connection itself?
There is no "different port Y". I don't understand what you mean.
mmm, think for example on the active side (rNFS client) say the TOE
stack assigned it port Y and also the Linux TCP stack assigned port Y
to the netperf client then when the server node sends data to the
client IP port Y - who is going to get it?
Or.
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...
