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.
v7:
1. Changed rss string to RSS to be consistent with other parts of the error codes
and documentation.
2. Corrected a few error messages
3. Changed error codes to use either 1 or 2 based on the situation
4. Added test cases in test-cmdline.c
