The linux-firmware package created from `build-linux-firmware.sh` in the vyos-build repository does not consult the `WHENCE` file for additional symbolic links that need to be created, resulting in many missing firmware files.
A concrete example of where this matters occurs with the Intel E810-series NICs utilizing the `ice` kernel mod and requiring a symlink at `intel/ice/ddp/ice.pkg` or else the NICs enter a failsafe mode incapable of performing much beyond basic forwarding.
The missing symlinks should be added into the vyos-linux-firmware package along with the link targets in order to prevent missing firmware files from causing incorrect/sub-optimal behaviour.
