[mc1322x] 6LowPAN multicast to "all link-local nodes"

[Daniel Berenguer]

Hi again,

I'm trying to do a ping over the "all link-local nodes" multicast
address ff02::01

ping6 -I tun0 ff02::1

but only the Econotag that acts as PC interface (tunslip6) is
responding to that ping.  The other Econotag only responds to unicast
pings, sent either to the link-local and link-global addresses.

May ipv6 multicast be disabled by default in Contiki's rpl-udp-client example?

Daniel.
