In linux kernel since version 3 (release Date: 2011-07-21)
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.
