I wonder if the abstraction is better be done such that you can also
configure the mode to trigger on (for example) TD and RNG. Then you'd
need one property per signal and then something like the following would
be possible:

p=/sys/class/leds/<led>
echo 1 > $p/tx
echo 0 > $p/rx
echo 1 > $p/rng

Best regards
