From 97550887973d04e344f5ccee392d7650d01f8f69 Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Tue, 4 Mar 2014 10:23:02 +0100 Subject: Bluetooth: make bluetooth 6lowpan as an option Currently you can have bluetooth 6lowpan without ipv6 enabled. This doesn't make any sense. With this patch you can disable/enable bluetooth 6lowpan support at compile time. The current bluetooth 6lowpan implementation doesn't check the return value of 6lowpan function. Nevertheless I added -EOPNOTSUPP as return value if 6lowpan bluetooth is disabled.
