246 Description: (RW) When retrieving the PHC with the PTP SYS_OFFSET_EXTENDED
247 ioctl, a system timestamp is made before and after the PHC
250 with the PHC time. This estimate may be wrong, as it depends
251 on PCI latencies, and when the PHC time was latched
255 retrieved PHC time.

| D | timestamping.rst | 627 There are situations when there may be more than one PHC (PTP Hardware Clock)
629 user to select which PHC to use for timestamping Ethernet frames. Instead, the
630 assumption is that the outermost PHC is always the most preferable, and that
652 I/O, they do have their own PHC). It is typical, but not mandatory, for all
653 interfaces of a DSA switch to share the same PHC.
773 But a MAC driver that is unaware of PHC stacking might get tripped up by
784 described above, in the case of a stacked PHC system, this condition should
785 never trigger, as this MAC is certainly not the outermost PHC. But this is
