Hardware timestamps can be exposed to userspace in raw hardware format (hwtstamp) as well as converted to system time (syststamp). The second variant is deprecated and only implemented by this driver. The preferred method of hardware timestamp generation is to combine hwtstamp with a device PTP clock. Octeon has its own PTP library that relies on a shared memory interface to the PTP clock device. Signed-off-by: Willem de Bruijn <willemb@google.com> Signed-off-by: David S.
