net: mscc: ocelot: annotate which traps need PTP timestamping
The ocelot switch library does not need this information, but the felix DSA driver does. As a reminder, the VSC9959 switch in LS1028A doesn't have an IRQ line for packet extraction, so to be notified that a PTP packet needs to be dequeued, it receives that packet also over Ethernet, by setting up a packet trap. The Felix driver needs to install special kinds of traps for packets in need of RX timestamps, such that the packets are replicated both over Ethernet and over the CPU port module. But the Ocelot switch library sets up more than one trap for PTP event messages; it also traps PTP general messages, MRP control messages etc. Those packets don't need PTP timestamps, so there's no reason for the Felix driver to send them to the CPU port module. By knowing which traps need PTP timestamps, the Felix driver can adjust the traps installed using ocelot_trap_add() such that only those will actually get delivered to the CPU port module.
