Firmware requirement

Separate firmware requirements have not been verified; no declaration is not evidence that none is needed. This is a driver-family list, not a per-device requirement. Optional features and other chips may use different files. Presence is checked against linux-firmware WHENCE File and Link records, including patterns.

Firmware	Manifest check

Firmware packaging varies by distribution; consult Debian firmware guidance or Arch network setup guidance. A missing manifest entry does not mean the device is unsupported.
