Thank you all for the fast replies, I tried to bring the interface
down but didn't realize it was brought back up by ifplugd. I can
confirm that it was ifplugd problem and the solution from Michael
works perfectly, now I just need to add a bootup script to configure
the wpan0/lowpan0 interfaces after reboot.
