+Subject: [PATCH] feat(kernel-modules): add Qualcomm IPC router to enable USB
+
+The x13s, and possibly other Qualcomm based devices need the QC
+IPC router driver in order to enable USB. Without it, its not
+possible to boot from USB-C attached disks.
+
+IPC in this case is Inter _Processor_ Communication and forms
+the message bus used to communicate between differing processing
+elements in a given system/SoC running and managing various
+hardware devices. This means that while it appears this driver
+should be in the dracut network modules that is incorrect
+because its not for enabling host networking in the initrd,
+but rather for communicating with other hardware blocks.
+
+Those other blocks aren't limited to modems, but any SMD (shared
+memory device), which on QC based machines includes the audio DSPs,
+RPM (resource power manager) and of course the application
+processor cores linux is running on.
