Thanks a lot for working on IPFix!  I don't have IPFix expertise, and I
don't think the other OVS committers have much either, so I need to ask
some dumb questions to better understand the implications of this patch.

Actually, maybe I just need to ask one.  This changes the wire format of
the IPFix reports that go out.  Will this require changes to IPFix
collectors that understood the previous format, that is, is the new
format backward compatible with collectors that expected the previous
format?  I understand that IPFix uses a template format to tell
collectors the format of what it's sending, but it's not clear to me
whether or not that prevents this kind of compatibility issue.

Thanks,

Ben.
