Subject: [net-next 05/11] ixgbe: fix driver version initialization in firmware

From: Jacob Keller <jacob.e.keller@...el.com>

This patch fixes an issue with storing the driver version for the
firmware. If the os does not support the particular firmware
management tools, the firmware requires a driver version to be written
as 0xFFFFFFFF rather than the actual driver version.
