fw4/nftables - performance seriously degraded after upgrade to 22.03.5 (from 21.03)

Not really. But I might not have followed the best practices as this
is my first run on ucode/nftables:

https://github.com/luizluca/firewall4/tree/log_limit

It needs some more tests on cases that I'm not using in production and
a test if it can avoid DoS the router.
