Subject: [net-next v2 0/2] tcp: add CMSG+rx timestamps to rx. zerocopy

From: Arjun Roy <arjunroy@...gle.com>

Provide CMSG and receive timestamp support to TCP
receive zerocopy. Patch 1 refactors CMSG pending state for
tcp_recvmsg() to avoid the use of magic numbers; patch 2 implements
receive timestamp via CMSG support for receive zerocopy, and uses the
constants added in patch 1.

v2: Fixes various stylistic comments and introduces a helper method
to reduce indentation.

Arjun Roy (2):
  tcp: Remove CMSG magic numbers for tcp_recvmsg().
  tcp: Add receive timestamp support for receive zerocopy.
