Yeah, wasn't entirely sure on this one. It fixes a problem, but it's
not exactly a new one. A quick look at git history suggests this might
actually be something that technically pre-dates the move to git in
2005, but only really became a problem with some additional far more
recent infrastructure (tc and friends). I can resubmit it as net-next
if that's preferred.
