Irrespective of the type of the key used, the user would want to change the hash key if he/she is not satisfied with the effectiveness of the default hash-key in spreading the incoming flows evenly across the RSS queues. This patch set provides support for configuring the RSS hash-key via the ethtool interface. The patch set consists of: a) ethtool user-land patches b) ethtool kernel patch c) be2net patch that implements the ethtool hooks
