hai...

I enabled the lowpan and wpan interfaces by using:

$ iz add wpan-phy0
$ ip link set wpan0 address a0:0:0:0:0:0:0:1
$ ifconfig wpan0 up
$ iz set wpan0 22 1 15                        //22:panid,1:short
address,15:channel number
$ 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


I am able to see the two interface:

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
          TX packets:0 errors:0 dropped:0 overruns:0 carrier: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
          UP BROADCAST RUNNING NOARP  MTU:127  Metric:1
          RX packets:390 errors:0 dropped:0 overruns:0 frame:0
          TX packets:2486 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:300
          RX bytes:15789 (15.4 KiB)  TX bytes:56803 (55.4 KiB)


I am able to send the packet over the wpan interface from user space by using
the IEEE-802.15.4 sockets. When i use sendmsg() the packet is including MAC
header and payload.

My question how to use the enabled lowpan interface and how to send and receive
the packets ?
