Subject: [net-next v2 0/2] tcp: add CMSG+rx timestamps to rx. zerocopy
Date: Wed, 20 Jan 2021 16:41:46 -0800 [thread overview]
Message-ID: <20210121004148.2340206-1-arjunroy.kdev@gmail.com> (raw)
From: Arjun Roy <arjunroy@google.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.
