Hi,
I'm using OpenWRT CHAOS CALMER (Bleeding Edge, r46141) with a Ralink
MT7628 Board and Linux 4.1.0.
I have set up a new interface:
iwpan dev wpan0 set pan_id 0xbeef
ip link set wpan0 up
ip link add link wpan0 name lowpan0 type lowpan
ip link set lowpan0 up
Here is the settings:
root@OpenWrt:/# ifconfig
lowpan0 Link encap:UNSPEC HWaddr
05-38-09-06-90-E0-5E-3E-00-00-00-00-00-00-00-00

root@OpenWrt:/# ip link

pan_id 0xbeef

min_be 3

max_csma_backoffs 4
lbt 0
Then I try to ping6 another board using the lowpan0 interface:
ping6 -I lowpan0 fe80::a8af:ac69:e53e:c7f1
All packets fail but more than that ifconfig tells me that no packet
have been sent:
root@OpenWrt:/# ifconfig
lowpan0 Link encap:UNSPEC
....
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
wpan0 Link encap:UNSPEC
...
RX bytes:0 (0.0 B) TX bytes:75 (75.0 B) (--> this is when I
set up lowpan0)
In the ip link command, I'm wondering why I've got [825] for the
lowpan0 interface?
Why those packets are not transmitted over all the layers?
Let me know if you need more info.
