From: Dumitru Ceara <dceara@redhat.com>

This is a backport of d7514abe117. Its original commit message is
below, including the original sign-offs and acks.

-------------------------

It's useful to differentiate between ingress and egress pipelines in the
ACL logs.  To achieve this we determine the direction by interpreting the
openflow table ID when processing packets punted to pinctrl by "log()"
action.
