From: Jesse Brandeburg <redacted> The kernel now has common statistics for transmit timestamps, so implement them in the ice driver. use via ethtool -I -T eth0 Reviewed-by: Jacob Keller <jacob.e.keller@intel.com> Reviewed-by: Jakub Kicinski <kuba@kernel.org> Reviewed-by: Hariprasad Kelam <redacted> Reviewed-by: Simon Horman <horms@kernel.org> Signed-off-by: Jesse Brandeburg <redacted> Tested-by: Rinitha S <redacted> Reviewed-by: Aleksandr Loktionov <redacted> Signed-off-by: Jacob Keller <jacob.e.keller@intel.com> --- drivers/net/ethernet/intel/ice/ice_ethtool.c | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+)
