Setting RAT preference in MBIM?

[Markus Gothe]

Yes, the lib is rather complex... I try reading the spec instead (discovering new things every day the last 14 days)...

However for SMS-handling mmcli+libmbim was gold when debugging my PDU's. :-)

The 'mbim-network'-script ought to be updated to turn on radio as the first thing it does, dont you think?

We could have PIN-code in the conf-file as well.

(I might fix the script if I get the dlink working on 3.13.x)
