Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/jesse/openvswitch
Jesse Gross says:
====================
Open vSwitch
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.
* 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.
====================
