I would just make a L2 PTP event message from a specific source
address, just like the phyter does.

Use Ethertype ETH_P_1588 (0x88f7), and make sure the "general" bit
(0x8) of the messageType field (the first payload byte, at offset 14)
is clear.

dp83640.c uses a magic source address to identify a time stamping
status frame:

static u8 status_frame_src[6] = { 0x08, 0x00, 0x17, 0x0B, 0x6B, 0x0F };
