a few years back we decided to merge bluetooth-next via John's wireless-next tree so that any interaction with 802.11 and Bluetooth can be sorted out in John's tree. We are now also merging NFC into the wireless-next tree.

So it might be a good idea to include the 6LoWPAN parts into the wireless-next tree as well. If there are conflicts with 802.15.4, maybe that should also go through his trees.

If you want I can also take the net/6lowpan stuff through bluetooth-next tree.

Regards

Marcel
