Hi Jack,
DEVICE_SWI is intended for non-GOBI Sierra Wireless devices or DELL 
branded version of them which the DW5934e isn't.
A DEVICE_SWI interface layout has a QMI/RMNET function in interface #8 
which the DW5934e hasn't.
So the DW5934e does not belong in qcserial, it should instead be added 
in the serial option driver.

thanks
Lars
