Just to be clear in both of our approaches, the contents of the 
RTA_ENCAP data is interpreted by the encap owner. Therefore, if the mpls 
encap doesn't consist of nested attributes then it doesn't preculde 
vxlan, for example, consisting of nested attributes.

I do agree though that the netlink format for specifying mpls encap 
should support nested attributes from day 1 to allow it to be extended 
without breaking the ABI.

Thanks,
Rob
