| H A D | timestamping.rst | 678 There are situations when there may be more than one PHC (PTP Hardware Clock)
680 user to select which PHC to use for timestamping Ethernet frames. Instead, the
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
841 PHC system, this is incorrect because this MAC driver is not the only entity
849 that PTP timestamping is not enabled for anything other than the outermost PHC,
