I'd be tempted to just put this in it's own file. As you say, it
doesn't really fit in either of the two existing ones.

I think this function should be given a more generic name and possibly
moved to packet.c.

Don't we need to carry this information along as well similar to skb->mark?
Also, is there a reason to not have the code for push/pop actions here as well?
