>Description:
Activity LEDs on all of my i8254x cards don't blink even though tx/rx occurs.
This is a driver's problem because they blink under FreeBSD.
I'm not sure whether there is no i8254x card which blinks its activity LED.
>How-To-Repeat:
always repeat. (see description)
>Fix:
A patch follows. It enables LED blinking in wm_init().
