Bluetooth: Enable 6LoWPAN support for BT LE devices
This is initial version of
http://tools.ietf.org/html/draft-ietf-6lo-btle-00
By default the 6LoWPAN support is not activated and user
needs to tweak /sys/kernel/debug/bluetooth/hci0/6lowpan
file.
The kernel needs IPv6 support before 6LoWPAN is usable.
