ethtool: Add a common function for drivers with transmit time stamping.
Currently, most drivers do not support transmit SO_TIMESTAMPING. For those that do support it, there is one appropriate response to the get_ts_info query. This patch adds a common function providing this response. Signed-off-by: Richard Cochran <richardcochran@gmail.com> Reviewed-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S.
