Subject: [PATCH net 0/2] net: fix the mirred packet drop due to the incorrect dst

This issue was found when using OVS HWOL on OVN-k8s. These packets
dropped on rx path were seen with output dst, which should've been
dropped from the skbs when redirecting them.

The 1st patch is to the fix and the 2nd is a selftest to reproduce
and verify it.

Davide Caratti (1):
  selftests: add a test case for mirred egress to ingress

  net: sched: act_mirred: drop dst for the direction from egress to
    ingress
