I have enabled PTP on RPi3 B+ by following the instruction given here. Now can you help me with a code to test PTP on Rpi. I am trying with one code, but with "SOF_TIMESTAMPING_TX_SOFTWARE" an input argument, but getting some error related to "ioctl" .
(http://www.cs.fsu.edu/~baker/devices/lxr/source/2.6.31.13/linux/Documentation/networking/timestamping/timestamping.c)

pi@raspberrypi:~ $ sudo ethtool -T eth0
Time stamping parameters for eth0:
Capabilities:
software-transmit (SOF_TIMESTAMPING_TX_SOFTWARE)
software-receive (SOF_TIMESTAMPING_RX_SOFTWARE)
software-system-clock (SOF_TIMESTAMPING_SOFTWARE)
PTP Hardware Clock: none
Hardware Transmit Timestamp Modes: none
Hardware Receive Filter Modes: none
