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.

Before you do any major changes you may want to take a look at what the SDR0_MFR register is set to on your board. It also has a portion that makes note of the ZMII mode. I was just looking at some stuff trying to pin-point my problem when I noticed that.
