Doesn't that basically boil down to the argument that "we can't merge

How about the inverse question: If this change is not acceptable, do
you have any other suggestion on to solve it? The hardware is what it
is, I can not will the source port information into existence, and
injecting packets on the wrong DSA port feels even more dirty to me.

I suppose you're right, I don't have any better suggestion.
