Evgeniy Kochetov 63c5e51ebc sock: Add sock_impl option to disable receive pipe
Receive pipe reduces number of system calls and gives significant
performance improvement with kernel TCP stack and relatively small IO
sizes. With user space TCP/IP implementations there are no system
calls and double buffering introduced by pipe has negative impact on
performance. Receive pipe remains enabled by default.
