Instead, the 673 assumption is that the outermost PHC is always the most preferable, and that 695 I/O, they do have their own PHC). It is typical, but not mandatory, for all 696 interfaces of a DSA switch to share the same PHC. 816 But a MAC driver that is unaware of PHC stacking might get tripped up by 827 described above, in the case of a stacked PHC system, this condition should 828 never trigger, as this MAC is certainly not the outermost PHC. But this is 835 PHC system, this is incorrect because this MAC driver is not the only entity 843 that PTP timestamping is not enabled for anything other than the outermost PHC,
