--- Comment #10 from Roger Pau Monné roy...@freebsd.org ---
Now I remember the problem with the current patch, if the set of available
options is different between the hosts we will fall back to enabling
everything. The attached patch should solve this, trying to preserve as many
options as possible when migrating. I've tested it and it seems to work fine,
but currently I don't have two hosts that expose different xn features.

I'm running a tinderbox now to make sure I don't break anything else, once that
finishes I will commit it.

  netfront: preserve configuration across migrations

  Try to preserve the xn configuration when migrating. This is not always
  possible since the backend might not have the same set of options
  available, in which case we will try to preserve as many as possible.
