[PATCH v2 net-next 0/5] Local Checksum Offload

Tested with a VXLAN tunnel over a device that doesn't support inner checksum
 offload (so the checksum will have been done in sw by validate_xmit_skb()).

Changes from v1:
 * Enabled support in more encapsulation protocols.
   I think it now covers everything except GRE.
 * Wrote up some documentation covering TX checksum offload, LCO and RCO.

Edward Cree (5):
  net: local checksum offload for encapsulation
  net: enable LCO for udp_tunnel_handle_offloads() users
  net: vxlan: enable local checksum offload
  fou: enable LCO in FOU and GUE
  Documentation/networking: add tx-offloads.txt to explain LCO
