hai...

I used the following commands to enable the wpan and lowpan interface...
# iz add wpan-phy0
# ip link set wpan0 address a0:0:0:0:0:0:0:1
# ifconfig wpan0 up
# iz set wpan0 abcd 8001 11
# ip link add link wpan0 name lowpan0 type lowpan
# ip link set lowpan0 address a0:0:0:0:0:0:0:1
# ip link set lowpan0 up


while executing those command 8 packets are going out of the wpan interface...
What are those packets..?

and also the Link encap for both the packets is UNSPEC..   What is the reason
for this ?

lowpan0   Link encap:UNSPEC  HWaddr
A0-00-00-00-00-00-00-01-00-00-00-00-00-00-00-00
          inet6 addr: fe80::a200:0:0:1/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1281  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0

          collisions:0 txqueuelen:0
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

wpan0     Link encap:UNSPEC  HWaddr
A0-00-00-00-00-00-00-01-00-00-00-00-00-00-00-00

          RX bytes:124 (124.0 B)  TX bytes:397 (397.0 B)
