[PATCHv6 net-next 00/10] OVS conntrack support

[Joe Stringer]

The goal of this series is to allow OVS to send packets through the Linux
kernel connection tracker, and subsequently match on fields populated by
conntrack. This functionality is enabled through a new
CONFIG_OPENVSWITCH_CONNTRACK option.

This version addresses the feedback from v5, primarily checking the behaviour
is correct with different configurations such as disabling
CONFIG_OPENVSWITCH_CONNTRACK or disabling individual conntrack features like
connlabels.

The branch below has been updated with the corresponding userspace pieces:

Joe Stringer (10):
  openvswitch: Serialize acts with original netlink len
  openvswitch: Move MASKED* macros to datapath.h
  ipv6: Export nf_ct_frag6_gather()
  dst: Add __skb_dst_copy() variation
  openvswitch: Add conntrack action
  openvswitch: Allow matching on conntrack mark
  netfilter: Always export nf_connlabels_replace()
  netfilter: connlabels: Export setting connlabel length
  openvswitch: Allow matching on conntrack label
  openvswitch: Allow attaching helpers to ct action
