Currently, VyOS doesn't have any CLI command for PCIe Active State Power Management (ASPM). On some platforms (particularly small-form-factor/embedded boards using Intel igc/igb/ixgbe NICs), firmware doesn't grant the OS ASPM control (can't disable ASPM; OS doesn't have ASPM control in dmesg), and there's no BIOS toggle to disable it either. The only workaround today is to force it off via the pcie_aspm=off kernel boot parameter — but VyOS has no supported CLI path to set this persistently.

Currently, achieving this requires manually editing the per-image GRUB fragment under /boot/grub/grub.cfg.d/vyos-versions/<image>.cfg, which:

• Is outside the standard configure/commit model
• Does not survive add system image upgrades (each new image regenerates its own .cfg)
• Requires re-application after every image add

It could be a command like this:

set system option disable-pcie-aspm
