QMI protocol error (5): 'client-ids-exhausted'
This may force us to have something like a state file in /tmp with the IDs
currently allocated, so that ModemManager can re-use them if needed.
** QMI: A device may export multiple cdc-wdm interfaces, along with multiple
wwan interfaces. If this is the case, we should allow configuring multiple
bearers. Additional comments from Bjorn Mork:
"The code really should try to match the wwanX and cdc-wdmY devices by
USB interface and not by USB device. If we ignore the unfortunate 3.4
and 3.5 kernels, then a matching wwanX and cdc-wdmY set will always
share the same parent USB interface on QMI devices. Having the same
parent USB device is *not* sufficient."
