As an aside, there appear to be two major protocols that Qualcomm-based
devices speak.

The Qualcomm radios in most Android devices and the Qualcomm Gobi
product line speak QMI, which is partially implemented by the Android
smd_qmi.c driver and the codeaurora.org Gobi drivers.

Many other Qualcomm-based devices, including handsets and mobile
broadband cards instead speak QCDM.  Which is the protocol that the
ports I'm adding in this series use.
