Subject: i40e: Fix for blinking activity instead of link LEDs
Patch-mainline: v4.16-rc1
Git-commit: d95cd48060e69d7135e65e667777ab7ddb1c9846
References: bsc#1101816 FATE#325147 FATE#325149
This fix solves an issue occurring while calling i40e_led_set function
from the driver with "blink" parameter set as TRUE. This call resulted
in Activity LED blinking instead of Link LED, which may lead to errors
in physically identifying the port, since Activity LED may be blinking
for different reasons as well.
