KSZ8463 uses the KSZ9893 DSA TAG driver. However, the KSZ8463 doesn't
use the tail tag to convey timestamps to the host as KSZ9893 does. It
uses the reserved fields in the PTP header instead.

Sigh, some of the marvell switches seem to be doing the same thing.
Is this the _only_ option this switch supports?

Reserved fields in protocols are generally reserved, not free to use.

No sadly, it's the only option this switch supports.


Best regards,
