Add the NETDEV_TX_STAMP capability flag to d_features, next to the existing NETDEV_RX_STAMP, so a driver can declare that it delivers hardware TX timestamps. SIOCETHTOOL and ETHTOOL_GET_TS_INFO were already defined but not implemented. Add struct ethtool_ts_info, with the same layout as Linux, and handle SIOCETHTOOL in netdev_ioctl.c so that userspace (such as ptpd) can query the timestamping capabilities of an interface the same way linuxptp/ptp4l does on Linux: - ETHTOOL_GET_TS_INFO fills so_timestamping from d_features: RX_HARDWARE | RAW_HARDWARE with NETDEV_RX_STAMP, otherwise RX_SOFTWARE | SOFTWARE (the stack stamps received packets with CLOCK_REALTIME), and TX_HARDWARE | RAW_HARDWARE with NETDEV_TX_STAMP. phc_index is -1, tx_types and rx_filters are zero. - Any other ethtool command is passed to the driver's d_ioctl when CONFIG_NETDEV_IOCTL is enabled, otherwise -ENOTTY is returned.
