Description

Would it be possible to detect if you have an Intel I225-V controller and add the following parameters to the kernel if present:
Disable power management for all PCIe ports ( pcie_port_pm=off )
Disable PCIe active-state power management (ASPM) ( pcie_aspm.policy=performance )

Reason for this being that on fresh install of CachyOS the network seems to be working fine at first but the driver for the adapter crashes after some time.

Research direction

Start at chwd's hardware-detection and configuration entry points and trace how kernel parameters are assembled for detected hardware. Verify the I225-V match and both requested parameters, then confirm the resulting configuration includes them without changing behavior for other hardware.
