[Support Request] r8156.ko for DSM 7.2.2-72806 (DS1520+ / RTL8156B Adapter)

[1maaat]

Description of the problem

Hello 👋

First of all, thank you for maintaining this amazing driver. It’s incredibly valuable for Synology users with modern USB Ethernet adapters.

I’d like to request a precompiled r8156.ko module for the following configuration:

• NAS model: Synology DS1520+
• Architecture: x86_64 / Geminilake
• DSM version: 7.2.2
• Build number: 72806
• Kernel: Linux 4.4.302+ #72806 SMP Thu Sep 5 13:44:44 CST 2024
• Adapter: Realtek RTL8156B-based USB 3.2 Gen 2 to RJ45 5GbE (Vendor/Product ID: 0bda:8157) :
• Connection: plugged into the front USB port of the NAS, connected to a Freebox Ultra 2.5G port via Cat 8 cable

The module r8152.ko from the current .spk installs successfully, and the interface (eth2) is detected, but no link is established (ethtool shows “Link detected: no”, and only 1000baseT advertised).

After inspecting lsusb, I can confirm this is a RTL8156B device, which seems to require r8156.ko or a version of r8152.ko built with proper support enabled.

If you have the possibility to share a compiled r8156.ko (or compatible .spk) for DSM 7.2.2 build 72806, it would be hugely appreciated.

Thanks again for your time and work 🙏
Let me know if I can help test or validate anything!
