[PATCH] MTX-1: make au1000_eth probes all PHY addresses

[PATCH] MTX-1: make au1000_eth probes all PHY addresses

[Florian Fainelli]

From: Florian Fainelli <florian@openwrt.org>

When au1000_eth probes the MII bus for PHY address, if we do not set au1000_eth
platform data's phy_search_highest_address, the MII probing logic will exit
early and will assume a valid PHY is found at address 0. For MTX-1, the PHY is
at address 31, and without this patch, the link detection/speed/duplex would not
work correctly.

Thanks, applied to 2.6.34+.  Note that while you added a
CC stable@kernel.org that address was not actually on the mail's cc list!
