This is not free software!

Most realtek recent drivers have a nonfree firmware as byte arrays in the vendor ID registered C files. The files have GPL license headers; but the corresponding source code is incorrect: it should be [code]2357:011e[/code] (see: https://h-node.org/issues/view/en/380). apparently not available.
[/p]
for example:
[list][*]hal/rtl8812a/hal8812a_fw.c[/*][/list]
(from sources: aircrack-ng / rtl8812au / rtl8812au-aircrack-ng / rtl8812au-ng)
[p]
Someone would need to liberate/replace those firmwares. The architecture of the CPU of these WiFi cihp is 8051; so it's already possible to de-compile the code with radare2, and we know the entry point.

Tested with a Guix System, using the [code]rtl8812au-aircrack-ng-linux-module[/code] module. Related entries:

The configuration looked like so: [h1]NOTE: the actual VID/DID is 2357:011e[/h1]

The performance appears very good on the 5 GHz band (OK on the 2.4 GHz band). It saturated my 50/10 MBPS link easily from across the apartment on the 5 GHz band.
