Hunk #2 succeeded at 480 (offset -4 lines). 1 out of 2 hunks FAILED We need to get the IEEE 802.15.4 changes merged through John's wireless-next tree. IEEE 802.15.4 going straight into net-next and Bluetooth going into wireless-next will not work out smoothly when both technologies are now utilizing 6LoWPAN and we are heavily working on 6LoWPAN. John, how confident are you with pulling net-next into wireless-next at this point in time? Regards Marcel
