On Spectrum-1, timestamps arrive through a pair of dedicated events: MLXSW_TRAP_ID_PTP_ING_FIFO and _EGR_FIFO. The payload delivered with those traps is contents of the timestamp FIFO at a given port in a given direction. Add a Spectrum-1-specific handler for these two events which decodes the timestamps and forwards them to the PTP module. Add a function that parses a packet, dispatching to ptp_classify_raw(), and decodes PTP message type, domain number, and sequence ID. Add a new mlxsw dependency on the PTP classifier. Add helpers that can store and retrieve unmatched timestamps and SKBs to the hash table added in a preceding patch. Add the matching code itself: upon arrival of a timestamp or a packet, look up the corresponding unmatched entry, and match it up. If there is none, add a new unmatched entry. This logic is the same on ingress as on egress. Packets and timestamps that never matched need to be eventually disposed of. A garbage collector added in a follow-up patch will take care of that. Since currently all this code is turned off, no crud will accumulate in the hash table.
