Subject: [net-next 0/2] Adds CMSG+rx timestamps to TCP rx. zerocopy
Date: Fri, 11 Dec 2020 10:44:17 -0800 [thread overview]
Message-ID: <20201211184419.1271335-1-arjunroy.kdev@gmail.com> (raw)
From: Arjun Roy <arjunroy@google.com>
This patch series provides 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.
Arjun Roy (2):
tcp: Remove CMSG magic numbers for tcp_recvmsg().
tcp: Add receive timestamp support for receive zerocopy.
