bareudp: Fixed bareudp receive handling
Reverted commit "2baecda bareudp: remove unnecessary udp_encap_enable() in bareudp_socket_create()" An explicit call to udp_encap_enable is needed as the setup_udp_tunnel_sock does not call udp_encap_enable if the if the socket is of type v6. Bareudp device uses v6 socket to receive v4 & v6 traffic CC: Taehee Yoo <ap420073@gmail.com> Fixes: 2baecda37f4e ("bareudp: remove unnecessary udp_encap_enable() in bareudp_socket_create()") Signed-off-by: Martin Varghese <martin.varghese@nokia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
