Subject: [PATCH v3 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 option.

v3:
1. ETHTOOL_GRXFHINDIR, ETHTOOL_SRXFHINDIR command numbers & structure
are left unchanged.
2. Introduced new command numbers & structure for ETHTOOL_GRSSH & ETHTOOL_SRSSH.
