None.

The code really was never designed for ports magically disappearing or
re-appearing again.  So you will have to carefully consider the side
effects, of which there might be many.

FWIW I gave up early on trying to make dynamic changes at run time (too many issues!)

Instead, I just do

    killall ptp4l; ptp4l --new-config-options

Thanks,
