2020-07-28Documentation: bareudp: Corrected description of bareudp module.Martin Varghese
Removed redundant words. Fixes: 571912c69f0e ("net: UDP tunnel encapsulation module for tunnelling different protocols like MPLS, IP, NSH etc.") Signed-off-by: Martin Varghese <martin.varghese@nokia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-07-20Documentation: bareudp: update iproute2 sample commandsGuillaume Nault
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. Signed-off-by: Guillaume Nault <gnault@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-02-24net: Special handling for IP & MPLS.Martin Varghese
Special handling is needed in bareudp module for IP & MPLS as they support more than one ethertypes. MPLS has 2 ethertypes. 0x8847 for MPLS unicast and 0x8848 for MPLS multicast. While decapsulating MPLS packet from UDP packet the tunnel destination IP address is checked to determine the ethertype. The ethertype of the packet will be set to 0x8848 if the tunnel destination IP address is a multicast IP address. The ethertype of the packet will be set to 0x8847 if the tunnel destination IP address is a unicast IP address. IP has 2 ethertypes.0x0800 for IPV4 and 0x86dd for IPv6. The version field of the IP header tunnelled will be checked to determine the ethertype. This special handling to tunnel additional ethertypes will be disabled by default and can be enabled using a flag called multiproto. This flag can be used only with ethertypes 0x8847 and 0x0800.

2020-02-24net: UDP tunnel encapsulation module for tunnelling different protocols like ↵Martin Varghese
MPLS, IP, NSH etc. The Bareudp tunnel module provides a generic L3 encapsulation tunnelling module for tunnelling different protocols like MPLS, IP,NSH etc inside a UDP tunnel.
