![]() Ethtool priv flags implementation to enable or disable packet split, which is a hardware feature that inspects headers and will put headers in a separate DMA buffer from the payload data. The driver was automatically choosing to enable packet split in some cases and this gives the user the ability to turn it off/on explicitly. to query state: ethtool --show-priv-flags ethx to enable: ethtool --set-priv-flags ethx packet-split on to disable: ethtool --set-priv-flags ethx packet-split off Why would anyone want this? Because some environments benefit from header/data split in the receive buffer, and the driver defaults to one or the other depending on environment/kernel parameters. Why didn't you implement a generic ethtool control for this feature? Because Intel hardware is the only hardware that supports header/data split.
