I hope you all had a good Christmas and are looking forward to the 2015 new year celebrations! I've just published an article that I've had in development for a few months now. In this article (http://andybrown.me.uk/wk/2014/12/27/ksz8091rna) I document the development and testing of a development board for the Micrel KSZ8091RNA RMII ethernet PHY.

The schematic and gerbers are all available for you to improve and adapt to your own project and I've included the necessary changes to get it working with the TCP/IP stack in stm32plus.
