Here's my latest revision of some of the basics of the flow table. So
far it's basically just a renaming of the existing TCP connection
table. It's used for some new logging helpers, but otherwise doesn't
really function any differently.
However, this subset of the flow table work no longer bloats
flow/connection entries over a single cache line. That removes the
most prominent drawback of earlier revisions, meaning I think this
series is ready for merge now. Doing so will mean the later series
making more substantive changes to the flow behaviour are simpler.
