Today's implementation allow LED to blink based on the traffic
condition. We introduce an additional LED mode that reflects the RF
state.
The supported LED modes after this are:
IWL_LED_BLINK (current/default) - blink rate based on current Tx/Rx
traffic
IWL_LED_RF_STATE (new) -
LED OFF: No power/RF disabled, the LED is emitting no light
LED ON: Powered/RF enabled, the LED is emitting light
in a stable non-flashing state.
In order to provide the flexibility to support different LED
behavior per user/system preference we add "led_mode" iwlcore module
parameter.
