Most of these modes mean "ON on event", eg
"link" means ON when link up, else OFF. "
"tx" means ON on when transmitting, else OFF
"act" means ON when activity, else OFF
"copper" means ON when copper link up, else OFF
but some are blinking modes
"blink-act" means BLINK when activity, else OFF
Some modes can do ON and BLINK, these have one '/' in their name
"link/act" means ON when link up, BLINK on activity, else OFF
"link/rx" means ON when link up, BLINK on receive, else OFF
there is one mode, "1Gbps/100Mbps/10Mbps", which behaves differently:
blinks 3 times when linked on 1Gbps
blinks 2 times when linked on 100Mbps
blinks 1 time when linked on 10Mbps
(and this blinking is repeating, ie blinks 3 times, pause, blinks 3 times,
pause)
Some modes are disjunctive:
"100Mbps-fiber" means ON when linked on 100Mbps or via fiber, else OFF

"ptp" means it will light up when the PTP functionality is enabled on
the PHY and a PTP packet is received.
