We don't need it per port Jeff, you are being quite silly here. Right now
its permanently foo=0 for all ports and nobody has suffered anything too
horrible so being able to turn it off for all ports is clearly quite
sufficient for the neat future. If someone wants it per port they'll send
you a patch later.
