[Tinyos-help] b6lowPan---serial_tun errors

[Stephen Dawson-Haggerty]

Also not really a problem.  It's just letting you know that it read a packet
off the tun with an unsupported IP extension header: in particular, radvd
seems to generate multicast listener discovery (MLD) messages with an
options field that we drop.  You can figure out exactly what is going on
using wireshark, but it shouldn't cause any problems.
