Subject: [PATCH v9 net-next 0/7] openvswitch: support for layer 3 encapsulated packets

At the core of this patch set is removing the assumption in Open vSwitch
datapath that all packets have Ethernet header.  Support for layer 3 GRE
tunnels is also added by this patchset.

The implementation relies on the presence of pop_eth and push_eth actions
in datapath flows to facilitate adding and removing Ethernet headers as
appropriate. The construction of such flows is left up to user-space.

This series is based on work by Lorand Jakab, Thomas Morin and others.


This patch set is comprised of kernel patches against net-next.
It depends on:

    "[PATCH net-next 0/3] gre: receive also TEB packets for lwtunnels"

To aid review it and the above dependency is available at:

    tree: https://github.com/horms/openvswitch
    branch: me/l3-vpn
    tag: l3-vpn-v9

There is a companion patch set for the Open vSwitch user-space code
which I will post separately to the dev@...nvswitch.org mailing list as:

    "[PATCH v10 0/5] userspace: Support for layer 3 encapsulated packets"



Lorand Jakab (1):
  openvswitch: add layer 3 flow/port support

Simon Horman (6):
  net: add skb_vlan_deaccel helper
  openvswitch: set skb protocol when receiving on internal device
  openvswitch: add support to push and pop mpls for layer3 packets
  openvswitch: add layer 3 support to ovs_packet_cmd_execute()
  openvswitch: extend layer 3 support to cover non-IP packets
  openvswitch: use ipgre tunnel rather than gretap tunnel
