	  The IEEE 1588 standard defines a method to precisely
	  synchronize distributed clocks over Ethernet networks. The
	  standard defines a Precision Time Protocol (PTP), which can
	  be used to achieve synchronization within a few dozen
	  microseconds. In addition, with the help of special hardware
	  time stamping units, it can be possible to achieve
	  synchronization to within a few hundred nanoseconds.

	  This driver adds support for PTP clocks as character
	  devices. If you want to use a PTP clock, then you should
	  also enable at least one clock driver as well.

	  To compile this driver as a module, choose M here: the module
	  will be called ptp.

	  This driver adds support for using the eTSEC as a PTP
	  clock. This clock is only useful if your PTP programs are
	  getting hardware time stamps on the PTP Ethernet packets
	  using the SO_TIMESTAMPING API.

	  To compile this driver as a module, choose M here: the module
	  will be called gianfar_ptp.

	  Supports the DP83640 PHYTER with IEEE 1588 features.

	  This driver adds support for using the DP83640 as a PTP
	  clock. This clock is only useful if your PTP programs are
	  getting hardware time stamps on the PTP Ethernet packets
	  using the SO_TIMESTAMPING API.

	  In order for this to work, your MAC driver must also
73
	  implement the skb_tx_timestamp() function.

	  This driver adds support for using the PCH EG20T as a PTP
82 83 84 85 86 87 88
	  clock. The hardware supports time stamping of PTP packets
	  when using the end-to-end delay (E2E) mechansim. The peer
	  delay mechansim (P2P) is not supported.

	  This clock is only useful if your PTP programs are getting
	  hardware time stamps on the PTP Ethernet packets using the
	  SO_TIMESTAMPING API.
