hi,
i've now upgraded my firmware to 12.500.00.15.1803 Rev.A.
if i use this udev rule:
> SUBSYSTEM=="usb", ATTR{idVendor}=="03f0", ATTR{idProduct}=="581d",
> ATTR{bNumConfigurations}=="3", ATTR{bConfigurationValue}!="1"
> ATTR{bConfigurationValue}="1"
with the kernel patches provided, i get:

if i understand correctly, i should be able to start mbimcli or qmicli
(or mbim-network or qmi-network) and then be able to dhcp on wwan0?
