Merge branch 'tcp-zero-copy-receive'
Eric Dumazet says:
====================
tcp: add zero copy receive
This patch series add mmap() support to TCP sockets for RX zero copy.
While tcp_mmap() patch itself is quite small (~100 LOC), optimal support
for asynchronous mmap() required better SO_RCVLOWAT behavior, and a
test program to demonstrate how mmap() on TCP sockets can be used.
Note that mmap() (and associated munmap()) calls are adding more
pressure on per-process VM semaphore, so might not show benefit
for processus with high number of threads.
