Subject: [PATCHv5 net-next 0/2] net: enable udp v6 sockets receiving v4 packets with UDP

Currently, udp v6 socket can not process v4 packets with UDP GRO, as
udp_encap_needed_key is not increased when udp_tunnel_encap_enable()
is called for v6 socket.

This patchset is to increase it and remove the unnecessary code in
bareudp in Patch 1/2, and improve rxrpc encap_enable by calling
udp_tunnel_encap_enable().

v1->v4:
  - See patch 1/2.
v4->v5:
  - See patch 2/2.

Xin Long (2):
  udp: call udp_encap_enable for v6 sockets when enabling encap
  rxrpc: call udp_tunnel_encap_enable in rxrpc_open_socket
