I210 should definitely be working in the upstream Linux kernel. Please let
me know if it is not.

I'm uncertain what the Debian kernel version of igb looks like. It's
possible some critical patch is missing. You can try the latest version
(5.0.6) from e1000.sf.net and compiling with CFLAGS_EXTRA=-DIGB_PTP to see
if that driver works for you.
