This patch includes a big cleanup of the existing unused LED code, and adds support for controlling the LED. The link LED will blink if the device is not associated. The LED switches between 2 seconds on and 1 second off. If the device is associated the LED is switched on. The link LED also indicates packet TX. I do a little bit more led resetting than the vendor driver, but the device works now as expected for single LED and double LED devices.
