Looking up phy_device pointer from net_device requires looking into private data. This may be problematic if phy is handled separately from net_device. Pass phy_device pointer to link_update() function because looking up net_device pointer from phy_device is trivial, if needed. CC: Florian Fainelli <f.fainelli@gmail.com> CC: "David S.
