Do you happen to know what PHY you are using? Our Broadcom AC101L can do both RMII and MII, the hardware guy thinks all he might have to do is pop in a 50MHz crystal instead of the 25MHz one we have now. I think it might be worthwhile for me to try that, at least I'll be travelling down the road more well travelled.
We are using a Micrel KS8721B.
In terms of Ethernet I have recently broken it. We are booting our board from NAND. When a Debugger loads U-Boot into SDRAM everything works great. When our NAND Bootloader loads U-Boot into SDRAM both Ethernet and I2C have become broken. (Auto-Negotiation works but Transmit is broken, possibly Recieve Also.)
