The other factor I considered is scalability.  The OVS code as is
is not really friendly to SMP/NUMA scalability (but as Eric pointed,
neither is the classifier/action layer).  However, if this were to
become a problem in future I'm sure we could extend either the
interface as is (e.g., deploying multiqueue netlink sockets), or
migrate to something else.

I agree that adding new flows is a weakness of the OVS model
(obviously it was a trade off) that has some room to be improved.
But, as you say, that's more of a long-term project that I think can
be done incrementally over time.

So I don't really have any objections to this going into the tree.

Great, thanks for reviewing.
