The encoding will be based on struct ovs_vxlan_opts which is extended
as needed by appending new members to the end of the struct. Parsers
will look at the provided length to see which fields are provided.

But this means that if there are two extensions that are conflicting
or if one is retired you still need to carry the earlier members of
the struct. Why not make them real netlink attributes?

I figured that due to the limited space available in the VXLAN header
the structure would never grow big. I have no problem converting this
to use Netlink attributes internally though. Will address this in v2.
