Merge branch 'vxlan_tx'
Tom Herbert says:
====================
vxlan: Don't use UDP socket for transmit
UDP socket is not pertinent to transmit for UDP tunnels, checksum
enablement can be done without a socket. This patch set eliminates
reference to a socket in udp_tunnel_xmit functions and in VXLAN
transmit.
Also, make GBP, RCO, can CSUM6_RX flags visible to receive socket
and only match these for shareable socket.
v2: Fix geneve to call udp_tunnel_xmit with good arguments.
====================
