Sorry, I was busy with other work so this got sidelined.
I've pushed what I hav atm to
https://git.breakpoint.cc/cgit/fw/bpf-next.git/log/?h=nf_bpf_hooks_07
I had no time so far to do the testing needed for a new official
submission (e.g. bpf_link_info).
Compared to last uapi this now has a "flags" member that could be
used to indicate "need defrag" and so on.
I hope I can submit this again early April.
