Subject: [net-next 04/14] i40e: warn on newer/older firmware API rev

From: Shannon Nelson <shannon.nelson@...el.com>

If the firmware's API minor number is larger than the one expected, log
a warning and recommend driver SW update.
If the firmware's API major or minor number is smaller then the one expected
(n for major, n or n-1 for minor), log a warning and recommend NVM update.
