 The Realtek 11ac driver that simply devours its competitors.
 
 Devourer is a userspace re-implementation of Realtek's RTL88xxAU Wi-Fi
-driver (Jaguar family: RTL8812AU shipping on both bands, RTL8821AU
-shipping at 2.4 GHz, RTL8811AU supported via the 8812 code path,
-RTL8814AU RX-only), speaking to the chip directly through libusb. No
-kernel module, no `rtl8812au` DKMS tree — just a C++20 static library
-(`WiFiDriver`) plus two demo executables for RX and TX. It is the
-OpenIPC project's driver of choice for long-range video links built on
-top of cheap Realtek 11ac USB radios.
