Hi Jarno,
There's been a few iterations. The previous 64-bit version was using a
32-bit hash combined with a thread ID.
The 128-bit hash was based on a suggestion to have sufficient bits to
randomly generate the identifiers, however I've since shifted to using the
hash of the flow key---This allo
Joe,
What was the reason to go from 64-bit hash to 128-bit hash?

One of the current bottlenecks for revalidation performance is the cost of
assembling flow keys, masks and actions in the (linux) datapath. This series
seeks to reduce this cost by caching these elements in the udpif, and modifying
the datapath to skip sending these. To distinguish flows in the dat
