Description

Some network provider will provide non-dhcp network for the mobile.
Our current implementation doesn't setup static IP on the interface.

Manual configuration is working.

I had a look at T5965 and several discussions on the forum.
It seems as though under certain circumstances there will be no answer from DHCP even though I can see the DISCOVER being sent out the wwan0 interface, but the connection works if I setup the parameters that can be betrieved from ModemManager.

I would like to contribute a Python script that would be a drop-in replacement for dhcpd on such interfaces, would this issue be a proper place to discuss how to do it or should I use other channels for that?
