Subject: [PATCH v6 net-next 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 option.

v6:
1. Changed ethtool core to pass seperate pointers of indirection and hash key
   to the driver.
2. Added rss_context field to ethtool_rxfh structure to support multiple
   rss contexts.

Venkat Duvvuru (2):
  ethtool: Support for configurable RSS hash key.
  be2net: Support for configurable RSS hash key.
