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.
