[PATCH net-next 00/12] openvswitch: gre tunneling support.

Following patch series adds support for gre tunneling.
First six patches extend kernel gre and ip_tunnel modules
api so that there is more code sharing between gre modules
and ovs. Rest of patches adds ovs tunneling infrastructre
and gre protocol vport.

This series depends on "openvswitch tunneling preparation" patches.

Pravin B Shelar (12):
  gre: Simplify gre protocol registration locking.
  gre: Allow multiple protocol listener for gre protocol.
  gre: export gre_build_header() function.
  gre: export gre_handle_offloads() function.
  ip_tunnels: extend iptunnel_xmit()
  ip_tunnel: push generic protocol handling to ip_tunnel module.
  ip_tunnel: Add dont fragment flag.
  openvswitch: Copy individual actions.
  openvswitch: Add tunneling interface.
  openvswitch: Expand action buffer size.
  openvswitch: Optimize flow key match for non tunnel flows.
  openvswitch: Add gre tunnel support.
