in skb_clone() and friends.
Look at CONFIG_NET_CLS_ACT in net/core/skbuff.c

Yes this solves the case for dummy devices etc but how would
this cause a reset on the way from ingress to egress?

If the verdict is not to reset, there should be no clearing of those
fields from ingress -> egress until the skb is either freed or someone
else along the path resets it. Cloning or copying inherits. Am i missing
something?

I guess not but we might have a different understanding of when to
reset. From my point of view the only reason to reset any meta data
is to provide a certain scope a set of new fresh and clean sheets
to play around. Assuming we define global as everything and local
as per device/(ingress|egress) then we definitely need to invoke
a reset on the way over to egress.
