Richard, That's what I was afraid of. It seemed as though SW timestamping was working, but then I had a problem with my rootfs in my Linux build, and I didn't go back to try it again.
The Altera TSE MAC is listed as supported (whereas the ARM EMAC is not, specifically), would you suspect I would have more luck with that? It's only listed as supporting software timestamping - not PHC.

Should it work for the EMAC with the 4.1.22-ltsi-altera > kernel? IIRC, last time I looked, the altera HW and drivers are hopelessly broken. Ditto for the similar xilinx parts. Neither have drivers in mainline Linux, IIRC.
