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@openvswitch.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
