You have hardware time stamping...

                        ^^^^^^^^

and so you should use it by saying "hardware" here. (Or just omit this
line, since HW time stamping is the default.)

This is the expected behavior when there is only on PTP node on the
network. Do you have another node to test with?

If not, you can patch your igb/eth0 to the e1000e/eth1 and run two
instances of ptp4l. Then you should see some more activity.
