I also needed the 1PPS-out on SDP from i350 to give as 1PPS-in to our Timing FPGA for PTP. In our design SDP2 is used and the patch _does not_ work with SDP2 or SDP3, but only with SDP0 and SDP1.

The issue in igb_main.c and igb_ptp.c level/level_mask assignments.

Thanks for the heads up!
I only tested PEROUT using SDP0 and SDP1 and just assumed it would
work for SDP2 and SDP3 as well :-S

I will send out a v2 containing your suggestions later today.

Food for thought: Adding TimeSync registers dump in igb_ethtool would be really nice to watch what is happening in realtime. Currently there are no TS registers in its dump.

Yes agreed, that would indeed be very helpful.
