Make sure you stop PPP before trying to use QMI!

Hi,

If you try to start qmi-network with PPP still running via serial you will
get this cryptic error:
$ sudo qmi-network /dev/cdc-wdm0 start
Starting network with 'qmicli -d /dev/cdc-wdm0 --wds-start-network=
 --client-no-release-cid'...
error: couldn't start network: QMI protocol error (14): 'CallFailed'
call end reason (1): generic-unspecified
verbose call end reason (2,204): [internal] unknown-cause
Saving state... (CID: 8)
error: network start failed, no packet data handle
Clearing state...

This means you are still connected via the serial interface. Disconnect it
then it should work.

I just wanted to post this here in case someone Google's the error message.

Thanks,
Leith Bade
