Subject: [PATCH] [187/275] MIPS: MTX-1: Make au1000_eth probe all PHY addresses

2.6.35-longterm review patch.  If anyone has any objections, please let me know.

------------------
From: Florian Fainelli <florian@...nwrt.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.
