I think it will break some benchmark tools. The loopback device is for testing networking protocol stacks, so we shouldn't bypass the protocol processing. And anyone who has a performance problem of loopback device should turn to UNIX domain socket. =46or routers, how about letting users choose whether RPS mixes layer 4= info in? --=20 Regards=EF=BC=8C Changli Gao(xiaosuo@gmail.com)
