Changes since v3:
- split bpf_xdp_ct_add in bpf_xdp_ct_alloc/bpf_skb_ct_alloc and
bpf_ct_insert_entry
- add verifier code to properly populate/configure ct entry
- improve selftests
Changes since v2:
- add bpf_xdp_ct_add and bpf_ct_refresh_timeout kfunc helpers
- remove conntrack dependency from selftests
- add support for forcing kfunc args to be referenced and related selftests
Changes since v1:
- add bpf_ct_refresh_timeout kfunc selftest
