Add yt6801 driver support for Motorcomm LAN controllers in HAOS

[D1N0v]

Feature Request: Add support for Motorcomm YT6801 (yt6801 driver) in Home Assistant OS

I'm running Home Assistant OS 16.0 (Linux kernel 6.6+) on a mini-PC that has an integrated 2.5GbE LAN controller: Motorcomm YT6801.

This Ethernet controller is part of the motherboard (not a USB device). It has been supported in the mainline Linux kernel since version 6.6 via the yt6801 driver.

Background:
I originally installed Home Assistant OS back in version 2024.07, when support for YT6801 did not yet exist. Now I’ve fully updated to the latest HAOS 16.0, but the driver still does not appear to be present or loaded.

Steps to reproduce:

• Install HAOS 2024.07 on hardware with built-in YT6801 Ethernet
• Update to HAOS 16.0 (with kernel 6.6+)
• Check for driver: modprobe yt6801 → "No such file or directory"
• Check /lib/modules → directory not present
• No new Ethernet interface appears (e.g. via ip link)

Expected behavior:
The yt6801 driver should be available in the HAOS kernel so that integrated LAN hardware using YT6801 works out of the box.

Request:
Please include the yt6801 driver in HAOS builds — either built into the kernel or as a loadable module — to support modern mini-PCs with integrated 2.5GbE Motorcomm NICs.

Thank you!

I also bought a mini PC for home, it was a surprise that I couldn't connect it to the LAN port. But it worked when I set it up using a monitor and keyboard on my WiFi. It would be more convenient to use a wired connection. Thank you.

There is still no yt6801 driver in mainline. Last update I can find is from April where the Motorcomm team decided to suspend the upstreaming effort.

I can confirm this issue on GEEKOM Air12 Lite.

The onboard Ethernet controller (Motorcomm PCIe, likely YT6801 2.5GbE) is correctly detected in BIOS but not recognized by Home Assistant OS.

USB Ethernet adapters work without problems.

This confirms that the issue is missing yt6801 driver support in the HAOS kernel.

Please consider enabling yt6801 support, as more mini PCs are now shipping with Motorcomm 2.5G controllers.

Thank you.
