[PATCH net-next 0/6] Tunneling: Tunnel restructuring.

Following patch series restructure GRE and IPIP tunneling code
to make it modular. It adds ip_tunnel module which acts as
generic tunneling layer which has common code.

These patches do not change any functionality. 

Pravin B Shelar (6):
  GRE: Use RTNL for atomic protocol registration.
  GRE: Refactor GRE tunneling code.
  IPIP: Use ip-tunneling code.
  VXLAN: Fix vxlan stats handling.
  VXLAN: Use IP Tunnels tunnel ENC encap API
  tunnels: Use IP Tunnel stats APIs.
