Hi Martin,

I can not take these patches at this point.

checking file net/ieee802154/6lowpan_rtnl.c
Hunk #1 FAILED at 143.
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
