The kselftest framework uses a default timeout of 45 seconds for
all test scripts.
Increase the timeout to two minutes for the netfilter tests, this
should hopefully be enough,
Make sure that, should the script be canceled, the net namespace and
the spawned ping instances are removed.
Fixes: 25d8bcedbf43 ("selftests: add script to stress-test nft packet path vs. control plane")

Enable/disable tracing infrastructure while packets are in-flight.
This triggers KASAN splat after
e34b9ed96ce3 ("netfilter: nf_tables: avoid skb access on nf_stolen").
While at it, reduce script run time as well.

Start flood ping for each cpu while loading/flushing rulesets to make
sure we do not access already-free'd rules from nf_tables evaluation loop.
Also add this to TARGETS so 'make run_tests' in selftest dir runs it
automatically.
This would have caught the bug fixed in previous change
("netfilter: nf_tables: do not skip inactive chains during generation update")
sooner.
