[PATCH net-next v2 0/4] openvswitch tunneling preparation

Following patches are required but not directly related to ovs tunneling.
So I am sending them as separate series. These cleanups are already
there in out of tree ovs module.

Since ovs tunneling series depends on this, I am sending all patches
again.

Pravin B Shelar (4):
  openvswitch: Unify vport error stats handling.
  openvswitch: Simplify interface ovs_flow_metadata_from_nlattrs()
  openvswitch: Fix struct comment.
  openvswitch: make skb->csum consistent with rest of networking stack.
