There are various L3 encapsulation standards using UDP being discussed to
leverage the UDP based load balancing capability of different networks.
-MPLSoUDP (__ https://tools.ietf.org/html/rfc7510) is one among them.

The Bareudp tunnel module provides a generic L3 encapsulation support for
tunnelling different L3 protocols like MPLS, IP, NSH etc. inside a UDP tunnel.
Special Handling
----------------
+
The bareudp device supports special handling for MPLS & IP as they can have
multiple ethertypes.
-MPLS procotcol can have ethertypes ETH_P_MPLS_UC (unicast) & ETH_P_MPLS_MC (multicast).
+The MPLS protocol can have ethertypes ETH_P_MPLS_UC (unicast) & ETH_P_MPLS_MC (multicast).
IP protocol can have ethertypes ETH_P_IP (v4) & ETH_P_IPV6 (v6).
This special handling can be enabled only for ethertypes ETH_P_IP & ETH_P_MPLS_UC
with a flag called multiproto mode.
3) Device Usage
The bareudp device could be used along with OVS or flower filter in TC.
-The OVS or TC flower layer must set the tunnel information in SKB dst field before
-sending packet buffer to the bareudp device for transmission. On reception the
-bareudp device extracts and stores the tunnel information in SKB dst field before
