Documentation: bareudp: update iproute2 sample commands 



bareudp.rst was written before iproute2 gained support for this new
type of tunnel. Therefore, the sample command lines didn't match the
final iproute2 implementation.

2) Device creation with multiple proto mode enabled

2) Device creation with multiproto mode enabled



There are two ways to create a bareudp device for MPLS & IP with multiproto mode

enabled.

The multiproto mode allows bareudp tunnels to handle several protocols of the

same family. It is currently only available for IP and MPLS. This mode has to

be enabled explicitly with the "multiproto" flag.

    a) ip link add dev bareudp0 type bareudp dstport 6635 ethertype ipv4 multiproto



    b) ip link add dev  bareudp0 type bareudp dstport 6635 ethertype mpls

       For an IPv4 tunnel the multiproto mode allows the tunnel to also handle

       IPv6.



    b) ip link add dev bareudp0 type bareudp dstport 6635 ethertype mpls_uc multiproto



       For MPLS, the multiproto mode allows the tunnel to handle both unicast

       and multicast MPLS packets.
