Can you describe which CPUs are involved in receiving TCP packets?

I guess in the ideal case there is flow steering that ensures the incoming packets appear in the receive queue receive handled by the CPU where the application calls recv(2). So just one CPU?

Do those conditions arise automatically or does it require manual tuning? Is application support required?
