Subject: [PATCH v5 ethtool 0/2] patchset - Support for configurable RSS hash key

NIC drivers that support RSS use either a hard-coded value or a random value for the RSS hash key. 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 adds support for configuring the RSS hash-key via the ethtool interface using .X/-x option.

v5:
1. Added rss_context field to ethtool_rxfh structure to support multiple
   rss contexts.
