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.

Looks good. Travis results:
https://travis-ci.org/gvrose8192/ovs-experimental/builds/416979227
The errors are unrelated to this patch.
Thanks Yifeng!
