+          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.

+        help
+          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
+          implement the skb_tx_timetamp() function.
