Hi everyone,
Like many of you, I struggled to get the Motorcomm YT6801 2.5G chip working on Proxmox 9 (Debian 13). PCI Passthrough is notoriously unstable on these Intel N-series mini PCs due to D3cold/IOMMU issues.
I finally found a stable solution by installing the driver directly on the Proxmox host using the official Debian Trixie Backports. This allows for a native 2.5G connection via a Linux Bridge (vmbr) with zero stability issues.
I've documented the whole process and created a repository for anyone facing the same '1f0a:6801' identification nightmare.
Solution highlights:

Solution highlights:
- No manual 'make' needed (DKMS handles kernel updates).
- Stable 2.5G throughput.
- Compatible with Proxmox 9.x (Kernel 6.12+ / 6.17+).
