[ovs-dev] [GIT net-next] Open vSwitch

[Jesse Gross]

A set of updates for net-next/3.13. Major changes are:
 * Restructure flow handling code to be more logically organized and
   easier to read.
 * Previously flow state was effectively per-CPU but this is no longer
   true with the addition of wildcarded flows (megaflows). While good
   for flow setup rates, it is bad for stats updates. Stats are now
   per-CPU again to get the best of both worlds.
 * Rehashing of the flow table is moved from a workqueue to flow
   installation time. Before, heavy load could block the workqueue for
   excessive periods of time.
 * Additional debugging information is provided to help diagnose megaflows.
 * It's now possible to match on TCP flags.
