    Subject[18/87] MIPS: MTX-1: Make au1000_eth probe all PHY addresses
    2.6.37-stable review patch.  If anyone has any objections, please let us know.

    ------------------

    From: Florian Fainelli <florian@openwrt.org>

    commit bf3a1eb85967dcbaae42f4fcb53c2392cec32677 upstream.

    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.
