Subject: [PATCH 0/5] ipv4_tunnels: Modularize ipv4 tunneling.

From: Pravin Shelar <pshelar@...ira.com>

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. I have patch
to do same for VXLAN too.

In Addidtion to restructuring it adds demultiplexer for ipgre
protocol, so that linux kernel IPGRE module and OVS gre module
can co-exist.
Last patch adds linux state updates to tunnel device from
lower device.

Pravin Shelar (5):
  GRE: Add segmentation offload for GRE TAP device.
  GRE: Use RTNL for atomic protocol registration.
  GRE: Refactor code GRE code.
  IPIP: Use ip-tunneling code.
  IP_TUNNEL: follow state of lower device
