This patch adds support for fixed PHY connected in MII mode to cpmac. We allow external and dumb_switch module parameters to override the PHY detection process since they are always connected with MDIO bus identifier 0. This lets fixed PHYs to be detected correctly and be connected to the their corresponding MDIO bus identifier. Signed-off-by: Florian Fainelli <florian@openwrt.org> ---
