This is the last planned series of the netfilter-selftest-move.
It contains cleanups (and speedups) and a few small updates to
scripts to improve error/skip reporting.

I intend to route future changes, if any, via nf(-next) trees
now that the 'massive code churn' phase is over.

Got it.

The main thing that seems to be popping up in the netdev runner is:

# TEST: performance
#   net,port                                                      [SKIP]
#   perf not supported

What is "perf" in this case? Some NFT module? the perf tool is
installed, AFAICT..

Its looking for the pktgen wrapper script
(pktgen_bench_xmit_mode_netif_receive.sh).

I don't think it makes too much sense to have that run as part of the CI.

I can either remove this or move it under some special commandline
option, or I can look into this and see if I can get it to run.

Let me know, thanks.

Hm, never used it myself but it makes me think of the extended ksft
vars:

 | TEST_PROGS_EXTENDED, TEST_GEN_PROGS_EXTENDED mean it is the
 | executable which is not tested by default.

I hooked the tests which reliably pass up to patchwork now.
(The PW reporting is "combined" so basically the daemon will take 
them into account for the "contest" check).

On the debug kernels we have a bunch of tests failing due to timeout.
We multiply the timeout set in ksft settings by 2 for the debug kernel,
so in netfilter we give them 1000 sec, but looks like that's not enough.

Would you be willing to bump it up? I can override it in the config of
the runner, as last resort.

It runs for ~25m, so I'd say lets NOT have it run by default.

Thanks, I'll add a small wrapper via TEST_PROGS_EXTENDED so folks
can run the performance (pps match rate) manually.
