[PATCH net-next v5 0/4] GRE: Use flow based tunneling for OVS GRE vport.

Following patches make use of new Using GRE tunnel meta data
collection feature. This allows us to directly use netdev
based GRE tunnel implementation. While doing so I have
removed GRE demux API which were targeted for OVS. Most
of GRE protocol code is now consolidated in ip_gre module.

v5-v4:
Fixed Kconfig dependency for vport-gre module.

v3-v4:
Added interface to ip-gre device to enable meta data collection.
While doing this I split second patch into two patches.

v2-v3:
Add API to create GRE flow based device.

Pravin B Shelar (4):
  openvswitch: Move tunnel destroy function to oppenvswitch module.
  ip_gre: Add support to collect tunnel metadata.
  openvswitch: Use regular GRE net_device instead of vport
  gre: Remove support for sharing GRE protocol hook.
