681 assumption is that the outermost PHC is always the most preferable, and that
703 I/O, they do have their own PHC). It is typical, but not mandatory, for all
704 interfaces of a DSA switch to share the same PHC.
822 But a MAC driver that is unaware of PHC stacking might get tripped up by
833 described above, in the case of a stacked PHC system, this condition should
834 never trigger, as this MAC is certainly not the outermost PHC. But this is
