From: Troy Tan <troy_tan@xxxxxxxxxxxxxx>
This patch adds the routines used to communicate between the RTL8812AE (wifi)
device and the RTL8761AU (bluetooth) device that are part of the same chip.
Unlike other similar dual-function devices, this chip does not contain special
hardware that lets the firmware pass coexistence info from one part to the
other. As a result, this driver implements such communication as a kernel
socket.

V2 - Add comments explaining the routine that sends a message via the socket.
