Merge branch 'net_next_ovs' of git://git.kernel.org/pub/scm/linux/kernel/git/pshelar/openvswitch 



Pravin B Shelar says:

====================
Open vSwitch

First two patches are related to OVS MPLS support. Rest of patches
are mostly refactoring and minor improvements to openvswitch.

v1-v2:
 - Fix conflicts due to "gue: Remote checksum offload"
