Hi @wildy,

These changes are needed to make it working:

net: qmi_wwan: support "raw IP" mode
qmi_wwan: add support for Quectel EC21 and EC25
usbnet: allow mini-drivers to consume L2 headers
net: qmi_wwan: should hold RTNL while changing netdev type

Then, for EC21/25, in rawIP mode, issue:
echo "Y" > /sys/class/net/wwanX/qmi/raw_ip

Cheers,
Piotr
