It would add one extra call along the "normal" ethernet receive path,
and two calls along 802x-in-ethernet.
I'll attempt to measure the performance impact. Chances are that it
isn't noticeable on modern hardware, and the older hardware probably
cares more about the savings in wired kernel text pages ...
