IIRC, Ben had some issues with how phylib and the EMAC would need to interact. Not sure if he has those written down somewhere or not.

I have a large variety of boards that I can test with since the entire 4xx line relies on this driver for on-board network. josh -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
