Subject: [PATCH net-next 0/4] selftests: forwarding: Tests redirects between
 L3 and L2 devices

Following merge commit 8eb517a2a4ae ("Merge branch 'reset-mac'"), which
made several L3 tunnels reset the skb's mac header pointer after decap,
here's a selftest that validates this new behaviour.

Patch 1 adds a reusable script for setting up the base network and
tests ipip and gre tunnels. The following patches extend the selftest
to cover more tunnel types (sit, ip6gre, ip6tnl, vxlan-gpe and
bareudp).

Guillaume Nault (4):
  selftests: forwarding: Test redirecting gre or ipip packets to
    Ethernet
  selftests: forwarding: Test redirecting sit packets to Ethernet
  selftests: forwarding: Test redirecting ip6gre and ip6tnl packets to
    Ethernet
  selftests: forwarding: Test redirecting vxlan and bareudp packets to
    Ethernet
