Changes in v2: - Distinguish between L2 and L4 PTP packets v1 at: https://lore.kernel.org/netdev/20230626154003.3153076-1-vladimir.oltean@nxp.com/
Patch 3/3 fixes an issue with the ocelot/felix driver, where it would drop PTP traffic on RX unless hardware timestamping for that packet type was enabled.
Fixing that requires the driver to know whether it had previously configured the hardware to timestamp PTP packets on that port. But it cannot correctly determine that today using the existing code structure, so patches 1/3 and 2/3 fix the control path of the code such that ocelot->ports[port]->trap_proto faithfully reflects whether that configuration took place.
Vladimir Oltean (3): net: mscc: ocelot: don't report that RX timestamping is enabled by default net: mscc: ocelot: don't keep PTP configuration of all ports in single structure net: dsa: felix: don't drop PTP frames with tag_8021q when RX timestamping is disabled
