The issue has been fixed in the upstream Linux kernel:

  https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/include/uapi/linux/net_tstamp.h?id=e2c4cf7f98a519eb4d95532bfa06bcaf3562fed5

This commit is part of Linux 4.20. It has a "Fixes" tag, so it should
normally be backported to Linux 4.19 at some point, even though this
hasn't happened yet.

So instead of doing a work around in linuxptp, we'll use the upstream
Linux kernel fix.

Best regards,

Thomas
