Subject: [PATCH v4 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.

v4:
1. Edited ethtool_rxfh command description to fit into one physical line.
2. Edited rss_config description to explain how indirection table and hashkey
   are arranged in memory.
3. Added description about what "indir_size == 0xDEADBEEF" means.
