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

+         This driver adds support for using the PCH EG20T 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 ptp_pch.
