The problem has actually gotten worse since we've gotten rid of the

I wonder if the right approach is to simply ditch the per-port

Following patch adds mask index to mask cache from last
pakcet lookup in same flow. Index of mask is stored in
this cache. This cache is searched by 5 tuple hash (skb rxhash).

The common use case is a flow expiring during the lifetime of a TCP

It's much less likely in the megaflows era though.

If the message was received via a shared memory ring the frame
is usable as ofpbuf base directly without copying the buffer
unnecessarily. A new destructor() callback is introduced which
allows marking the frame unused after the ofpbuf has been
