Mailinglist changed to [0].

Please let me know which kernel, libnl3 and lowpan-tools version do you
use.

Also I need to notice you that I am working on a big rework. With new
userspace tools, etc... I need some time to bring it mainline. The bring
it mainline thing is currently in progress.

I am very busy right now.

can you try to use bleeding edge kernel? [0]

this looks fine.

mhhh, I didn't get such warning.

Just try a bleeding edge kernel and try again. Then we can see what's
going on there. Also set a eui-64 address (extended address) before
running "iz set". You can do that by "ip link set $WPAN_INTERFACE address $EXTENDED_ADDR".

exmaples for variables:

WPAN_INTERFACE="wpan0"
EXTENDED_ADDR="aa:aa:aa:aa:aa:aa:aa:aa"

Please do these steps while $WPAN_INTERFACE is down.
