When we tried using `ethtool -E' for qed we got burned for trying to use the magic value [1]. When we suggested extending it to allow some private data indications, Ben claimed that this entire ethtool infrastructure is a thing of the past, and we should try using MTD instead - a claim no one bothered to counter. Creating proprietary file-formats, filling them with metadata and complementary driver state-machines could easily overcome the original obstacle we faced. But it raises the question of whether these APIs are valid or obsolete.
