From 7f63d8302e6387db6c27b1ba38c088e185841206 Mon Sep 17 00:00:00 2001 From: Yifeng Sun Date: Thu, 16 Aug 2018 09:52:55 -0700 Subject: porting: Add fixes to support kernel 4.15.x This patch enables OVS kernel module to run on kernel 4.15.x. Two conntrack-related tests failed: - conntrack - multiple zones, local - conntrack - multi-stage pipeline, local This might be due to conntrack policy changes for packets coming from local ports on kernel 4.15. More survey will be done later.
