From 18722c247023035b9e2e2a08a887adec2a9a6e49 Mon Sep 17 00:00:00 2001 From: Jukka Rissanen Date: Wed, 11 Dec 2013 17:05:37 +0200 Subject: 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.

However sending the command for controller that handle stored link keys is important. This quirk allows a driver to disable the command if it knows that this command handling is broken.
