[Intel-wired-lan] [next PATCH S2 05/13] i40e: Fix for 10G ports LED not blinking

From: Piotr Marczak <piotr.marczak at intel.com>
On some hardware LEDs would not blink after command 'ethtool -p {eth-port}'
in certain circumstances. Now, function does not care about the activity
of the LED (though still preserves its state) but forcibly executes
identification blinking and then restores the LED state.
