599 user to select which PHC to use for timestamping Ethernet frames. Instead, the
600 assumption is that the outermost PHC is always the most preferable, and that
622 I/O, they do have their own PHC). It is typical, but not mandatory, for all
623 interfaces of a DSA switch to share the same PHC.
743 But a MAC driver that is unaware of PHC stacking might get tripped up by
754 described above, in the case of a stacked PHC system, this condition should
755 never trigger, as this MAC is certainly not the outermost PHC. But this is
762 PHC system, this is incorrect because this MAC driver is not the only entity
770 that PTP timestamping is not enabled for anything other than the outermost PHC,
