Hi Sean

This appear to be a copy of mmd_phy_indirect(). There are patches from
Russell King which made this a public function. Once Russell patches
make net-next, it would be nice to use mmd_phy_indirect(). But that
might be as a follow up patch, rather than now, depending on the order
of acceptance of the patches.
