I'm probably being stupid and very confused here. Appologies if it is
a stupid question.

For a particular test I assign a client to core 1 and a server to core
0. My first assumption was all the sending side kernel TCP/IP
processing will be done on core 1 and all the receiving side
processing on core 0. However, having looked at the linux TCP/IP code,
more specifically the loopback device code, when the loopbacks
dev_queue_xmit function gets called it simply passes the skb to the
netif_rx function. Therefore my question is thus, when i assign the
sending / receiving side to different cores is the actual TCP/IP
processing done the assigned sending / receiving cores ? or is TCP/IP
processing done on the sending side only until a certain point? or is
it simply a single core that does all the TCP/IP processing. If it's
the first two and you have any idea, could you point me where in the
kernel the cores the processing swap over.

Thanks for your help
