Hi, I made an effort some time ago to get the IPv6 ND messages working also for Bluetooth Low Energy 6lowpan interfaces. The initial discovery was that they get sent when the interface is not a point-to-point one. The point-to-point interface flag is removed in patch 4/4. In order to get the ND messages properly working, the MAC address for a BTLE interface needs fixing, it's only 48 bits compared to the 64 bits for 802.15.4. Patches 1/4 and 2/4 fix these common issues. Patch 3/4, which is more hackish than the others, the patch uses an array of length EUI64_ADDR_LEN to lowpan_header_decompress() in order not to overwrite anything These changes worked when tested against Zephyr, but that was on a 4.5.0-rc2 kernel. This time around I only forward-ported them to latest and tested that they compiled successfully. I hope these patches help with ND work moving forward in some way or another.
