Hello community,
I'm having connman version 1.31 along side with ofono running on my board.
When I activate a context on my 4G modem using ofono, connman creates two services: one is
cellular and the other is ethernet.
*AR Wired ethernet_XX_cable
*AO XXX cellular_XXX_context1
In this case, the ideal state is that connman reports only one cellular technology related
to the modem.
When digging into the logs, I feels like a new ethernet device is enumerated and connman
creates the appropriate service for it.
Knowing that my modem net interface is using "cdc_ether" driver, does anyone
have an idea about what could be the issue here?
Regards,
Bassem

From you description I understand that the modem creates an additional
ethernet interface? Could you post the corresponding logs (or post a
link to the logs)?
I am also not sure what the exact question is. I suspect you want to see
only one interface and not two..
Thanks,

Hello Daniel,
Exactly, my modem is creating an additional ethernet interface, and I don't know why.
Please find in the link below the full log of connman.

Hi Daniel,
Issue is fixed. Thank you for your help.
I used to have this:
# cat /sys/class/net/usb0/uevent
INTERFACE=usb0
IFINDEX=7
I changed my driver in the kernel to probe it as a wwan info device based on vid and pid .
Now I have the DEVTYPE correct:
# cat /sys/class/net/wwan0/uevent
DEVTYPE=wwan
INTERFACE=wwan0
IFINDEX=7
Below my kernel patch in case of anyone having the same issue.
PS: I'm using a Cinterion PLS8 modem.

Please also create a patch for Linux upstream. You are almost there.
Just add a commit message and send it to the right mailing list :)
