This system is using third-party repo's, i.e. neither Centos / RedHat, although it is clearly based on Centos. The repo's do not have any development tool-chains, so we would have to put together another system, build ethtool on that, create an rpm and then invalidate the third-parties warranty by installing it on the production system. I think we'll just boot into diagnostic mode and see what we can discern from there.
