Because it's a composite device.  Was this a trick question? :-)

To both drivers.  The device is similar to the 1199:68a3 device already
supported by both drivers.  It has a number of serial ports (depending
on how many features like GPS etc is enabled) supported by the "sierra"
driver and one ethernet interface speaking Sierra's HIP protocol
supported by the "sierra_net" driver.
