Daniel P. Carvalho d6d06c72ad Documentation/stm32f4: document the Ethernet PTP support.
The STM32F4 page did not say anything about the Ethernet MAC.

- Describe the time counter of the MAC and the options that enable the
  timestamping of received packets, the pulse-per-second output and
  the use of the counter as a high-resolution RTC.
- Describe the /dev/ptp0 clock that the driver registers: the
  operations it offers, the numbering, and that the timestamps of the
  received packets are values of the MAC counter and not of
  CLOCK_REALTIME, so they have to be compared with /dev/ptp0.
- Show how to start ptpd with them and a configuration that enables
  everything above.
- Say that the driver does not timestamp transmitted packets.
