Hi Ben,

the mainline version is fully featured and I envisage that the
openvswitch-datapath package can be removed from the archive at some point.
I would value your input on how that might be best achieved.

As for the compile problem below, this is intended by upstream,
though perhaps isn't appropriate for Debian. I'll take guidance
on that issue from upstream.
