From 4b2a6aed2115cd72faaffc92e03d6516e8113904 Mon Sep 17 00:00:00 2001 From: Craig Gallek Date: Wed, 10 Feb 2016 11:50:41 -0500 Subject: soreuseport: BPF selection functional test for TCP Unfortunately the existing test relied on packet payload in order to map incoming packets to sockets. In order to get this to work with TCP, TCP_FASTOPEN needed to be used. Since the fast open path is slightly different than the standard TCP path, I created a second test which sends to reuseport group members based on receiving cpu core id. This will probably serve as a better real-world example use as well. Signed-off-by: Craig Gallek Signed-off-by: David S.
