[PATCHv2 net-next 0/5] net: move more duplicate code of ovs and tc conntrack into nf_conntrack_ovs

[Xin Long <lucien.xin@gmail.com>]

We've moved some duplicate code into nf_nat_ovs in:

  "net: eliminate the duplicate code in the ct nat functions of ovs and tc"

This patchset addresses more code duplication in the conntrack of ovs
and tc then creates nf_conntrack_ovs for them, and four functions will
be extracted and moved into it:

  nf_ct_handle_fragments()
  nf_ct_skb_network_trim()
  nf_ct_helper()
  nf_ct_add_helper()

v1->v2:
  - In patch 1/5, fix the wrong option name 'NF_NF_CONNTRACK' used in
    net/openvswitch/Kconfig, found by kernel test robot.

Xin Long (5):
  net: create nf_conntrack_ovs for ovs and tc use
  net: extract nf_ct_skb_network_trim function to nf_conntrack_ovs
  openvswitch: move key and ovs_cb update out of handle_fragments
  net: sched: move frag check and tc_skb_cb update out of
    handle_fragments
  net: extract nf_ct_handle_fragments to nf_conntrack_ovs
