Hi Dear Pascal,

I started a RPL implementation on Linux Kernel (
https://github.com/joaopedrotaveira/linux-rpl) with basic functionalities
such as RPL OF0. I test it with several ARM boards (BBW, RPi and olinuxino)
but since kernels versions are so different to this boards, it was quite
difficult to maintain it working in all this devices at same time with so
many kernel netstack changes.

Anyway, after a while I got tired to try to support RPL on this older
kernels (3.8.y and 3.10.x for BBB and RPi) and moved forward to get MRH OF
working with rfc6551 and etx. This changes are not on github yet.

Using Contiki with rf23x radios and linux with same transceivers, I started
to implement MRH (etx) with rfc6551 but it has been difficult to get
transceivers delivery status from radio links. This kind of information is
not available yet on linux netstack and, after some emails exchanged with
6lowpan linux group and netdev group, I realised that if I want it done, I
should get it working first and then submit it. Unfortunately, I have no
available time to work on this, but I want to continue this implementation
as soon as possible.

BR,
João Pedro Taveira
