2.13 added multiple simultaneous data bearer support, but they should have been 
backwards compatible with those devices that don't support them.  Guess I broke 
something :)  Sorry about that.

What oFono tries to do is to cycle through three currently supported data formats:

- RAW_IP + QMAPv5 -> this enables multiple simultaneous bearer support.  There's 
also in theory RAW_IP + QMAPv4, but I don't have any devices that only support 
this format.
- RAW_IP -> Single context, no 802.3 framing overhead
- 802.3 -> Supported by really old Qualcomm devices.

Looks like the firmware is rejecting every single format we try to set it into. 
Do you know what format PinePhone uses?  Do you have libqmi / qmicli installed 
on the PinePhone to run some commands?  Something like:

qmicli --device=/dev/cdc-wdm0 
--wda-get-data-format=ep-type=hsusb,ep-iface-number=<InterfaceNumber>

where InterfaceNumber is what is being passed to gobi plugin from udevng inside 
the "InterfaceNumber" modem property.

For oFono 2.12, what do the contents of
/sys/class/net/<netif>/qmi/raw_ip
and
/sys/class/net/<netif>/qmi/pass_through

look like?  <netif> in this case is the QMI wwan network device, something like 
wwan0.
