| Subject: net: ena: add missing ethtool TX timestamping indication |
| |
| From: Arthur Kiyanovski <akiyano@amazon.com> |
| |
| [ 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. |
