The reason why the vxlan patches went out and then never included is
because they're not quite sufficient to implement the full protocol
including multicast learning. Initially it was hoped that
implementing the wire format would be a good first step but in reality
some more infrastructure work needs to be done first so we put it on
hold while we figured it out.
The goal of the infrastructure work would be to provide information
about the tunnel header in the flow lookup and then enable the
destination for outgoing packets to be set more flexibly from
userspace. It would then be possible to implement the current port
based mechanism, vxlan learning, and other things all from userspace
using this mechanism.
Is this something that you'd be interested in taking a shot at? If
so, I can provide some more details about what I was thinking.
