Compiling Realtek RTL 8152, 8156 and 8157 drivers for QNAP NAS

Note

This guide was last updated on 17th Feb 2025

Many QNAP NAS devices only come with 1Gbe network interfaces. These devices can easily benefit from a simple network upgrade by connecting the ubiquitious 2.5Gbe USB NICs from Realtek. Unfortunately, some of the older QNAP NAS systems do not support the newer r8156 based 2.5Gbe NICs or r8157 based 5Gbe NICs as they run an older 4.x linux kernel and the r8152 source files included with the older linux kernel are based off an older codebase that predates the 8156/8157 series.

With some elbow grease however, we can build support for the 2.5 & 5 Gbe adapters and easily upgrade functionality.

Upgrading to iOS/iPadOS 14.3 NOW

NOW IS POTENTIALLY THE LATEST YOU CAN DO THIS. 14.4 WILL LIKELY BE SERVED WHEN IT'S THE 26TH, IN UTC. THE END

Exporting your 2FA tokens from Authy to transfer them into another 2FA application

IMPORTANT - Update regarding deprecation of Authy desktop apps

Past August 2024, Authy stopped supported the desktop version of their apps:
See Authy is shutting down its desktop app | The 2FA app Authy will only be available on Android and iOS starting in August for details.

And indeed, after a while, Authy changed something in their backend which now prevents the old desktop app from logging in. If you are already logged in, then you are in luck, and you can follow the instructions below to export your tokens.

If you are not logged in anymore, but can find a backup of the necessary files, then restore those files, and re-install Authy 2.2.3 following the instructions below, and it should work as expected.

FFmpeg and libav's playbook: Advanced encoding options with hardware-based acceleration, NVIDIA's NVENC and Intel's VAAPI-based encoder.

Hello guys,

Continuing from this guide to building ffmpeg and libav with NVENC and VAAPI enabled, this snippet will cover advanced options that you can use with ffmpeg and libav on both NVENC and VAAPI hardware-based encoders.

For ffmpeg:

	#!/bin/ash

	list_pkgs() {
	opkg list-installed \| cut -f 1 -d " "
	}

	show_deps() {
	opkg depends $1 \| sed -e 1d -e 's/^\s*//'
	}

	#!/usr/bin/env python3
	import os, sys
	import argparse
	import struct
	from functools import reduce

	I finally managed to successfully downgrade the EFI firmware to version 1.6. Unfortunately that didn't make my hard drive work. However I'm going to reproduce my steps here so that the whole world can know what it takes:

	Download the EFI firmware update package from Apple. Here is the link I used for firmware version 1.6 for my late-2008 MacbookPro5,1: http://support.apple.com/kb/DL746
	WARNING! If you use the wrong firmware for you computer, bad things will almost certainly happen. This isn't my experience but it would probably brick your computer, meaning it will change from being a computer that can compute things to being a brick that just sits there. You have been warned!
	The EFI firmware update 1.6 comes as a .pkg file. Since it won't extract for you unless your computer needs the update, you will have to extract it yourself. The best way I found

	# Proxmox or other server kernel params cheap tune and secure.
	# Try it if you have heavy load on server - network or memory / disk.
	# No harm assumed but keep your eyes open.
