The big new thing here is netdetect which allows the

Browse Source 
firmware to wake up the platform when a specific network
 is detected. Along with that I have fixes for d3 operation.
 The usual amount of rate scaling stuff - we now support STBC.
 The other commit that stands out is Johannes's work on
 devcoredump. He basically starts to use the standard
 infrastructure he built.
