mv643xx_eth: use auto phy polling for configuring (R)(G)MII interface
The mv643xx_eth hardware has a provision for polling the PHY's MII management registers to obtain the (R)(G)MII interface speed (10/100/1000) and duplex (half/full) and pause (off/symmetric) settings to use to talk to the PHY. The driver currently does not make use of this feature. Instead, whenever there is a link status change event, it reads the current link parameters from the PHY, and programs those parameters into the mv643xx_eth MAC by hand. This patch switches the mv643xx_eth driver to letting the MAC auto-determine the (R)(G)MII link parameters by PHY polling, if there is a PHY present. For PHYless ports (when e.g. the (R)(G)MII interface is connected to a hardware switch), we keep hardcoding the MII interface parameters. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com>
