[ Upstream commit cf6d17fde93bdda23c9b02dd5906a12bf8c55209 ]
Current implementation of the driver calls skb_tx_timestamp()to add a software tx timestamp to the skb, however the software-transmit capability is not reported in ethtool -T.
This commit updates the ethtool structure to report the software-transmit capability in ethtool -T using the standard ethtool_op_get_ts_info(). This function reports all software timestamping capabilities (tx and rx), as well as setting phc_index = -1. phc_index is the index of the PTP hardware clock device that will be used for hardware timestamps. Since we don't have such a device in ENA, using the default -1 value is the correct setting.
