Drats, I was hoping there might be Open Source here.  I'm actually not
familiar with Netronome offerings.  I went to their web page and all
their Docs downloads require registration, so I should have guessed
same-old-same-old.  But you teased us with it, so I thought I would
ask.  Sorry for the trouble XOXOXOXO.  I'm not Canadian, as far as I
know.

You have access to the inside scope.  We don't.  Ok, I don't.  We
(think we) know what the traditional L2/L3 and OVS-style flow stuff
looks like, but you know more, but you can't show us in code so it's
frustrating.  Not your fault.  Just continue to guide us and give some
disclaimer when we're your close to some proprietary knowledge, but it
is relevant to the discussion.
