"Linux" generally speaking?

That's true only if "rm -rf net/netfilter/ net/ipv4/netfilter net/ipv6/netfilter"

Also, insert an XDP program... --> "non compliant"

And so on and so forth. :-)

It's local system policy, how do I react to packets.  If it doesn't
violate the min/max limits for ipv6 packets it emits onto the internet
I don't see this as something that can be seen as mandatory.
