Hmm. I haven't considered deviating in ebtables-nft-save format from
legacy one yet, but it may actually be no problem given that people
shouldn't switch between both. The only bummer might be if someone has a
custom script which then trips over the unknown non-comment line.

I'm undecided, but not against "breaking" with legacy save dumps per se.
If you think it's not a problem, we could just simplify things. OTOH
this is not a big patch, either so maybe not even worth the risk. :)

Thanks, Phil
