Link Fault Detection LED Activity (ISA Version)
When LFD is enabled and a fault occurs on a segment of the media conversion,
the various Link LEDs in that conversion will either blink or extinguish. LEDs may
react differently depending on the type of end devices in the conversion, whether
the McPC 10/100 is in Force 10 or Force 100 mode, where the fault occurs, etc.
