Hi Microchip,
as ACL based blocking of PTP traffic seems not to work, I tried to install MAC
based static lookup rules on the switch I successfully managed to block other
non-PTP traffic, but for PTP the lookup table entry (see below) seems not to
work. Incoming SYNC messages on port are still for
I need some help from Microchip, please read below.

Hi Tristram,
thank you for joining this thread.

This series adds support for PTP to the KSZ956x and KSZ9477 devices.
There is only little documentation for PTP available on the data sheet
[1] (more or less only the register reference). Questions to the
Microchip support were seldom answered comprehensively or in reasonable
time. So this is more
