Subject: [PATCH net-next 00/14] ipv6: Enable GUEoIPv6 and more fixes for v6 tunneling

This patch set:
  - Fixes GRE6 to process translate flags correctly from configuration
  - Adds support for GSO and GRO for ip6ip6 and ip4ip6
  - Add support for FOU and GUE in IPv6
  - Support GRE, ip6ip6 and ip4ip6 over FOU/GUE
  - Fixes ip6_input to deal with UDP encapsulations
  - Some other minor fixes


Tested:
   Tested a variety of case, but not the full matrix (which is quite
   large now). Most of the obivous cases (e.g. GRE) work fine. Still
   some issues probably with GSO/GRO being effective in all cases.

    - IPv4/GRE/GUE/IPv6 with RCO
      1 TCP_STREAM
      	6616 Mbps
      200 TCP_RR
	1244043 tps
        141/243/446 90/95/99% latencies
	86.61% CPU utilization
    - IPv6/GRE/GUE/IPv6 with RCO
      1 TCP_STREAM
	6940 Mbps
      200 TCP_RR

     - IP6IP6

	2576 Mbps
      200 TCP_RR
	498981 tps
	388/498/631 90/95/99% latencies

Tom Herbert (14):
  gso: Remove arbitrary checks for unsupported GSO
  gre6: Fix flag translations
  udp: Don't set skb->encapsulation with RCO
  fou: Call setup_udp_tunnel_sock
  fou: Split out {fou,gue}_build_header
  fou: Add encap ops for IPv6 tunnels
  ipv6: Fix nexthdr for reinjection
  ipv6: Change "final" protocol processing for encapsulation
  fou: Support IPv6 in fou
  ip6_tun: Add infrastructure for doing encapsulation
  ip6_gre: Add support for fou/gue encapsulation
  ip6_tunnel: Add support for fou/gue encapsulation
  ip6ip6: Support for GSO/GRO
  ip4ip6: Support for GSO/GRO
