Hi, Is there a way to enable HW timestamps with this Intel card using DPDK by means of the IEEE1588 set of function API? (Dpdk 20.08).
In my understanding the nic should support hardware time-stamping of RX packets if: "A separate PTP application would be required that communicates directly with the controller on the XL710" cit from https://community.intel.com/t5/Ethernet-Products/Does-intel-XL710-QDA2-support-HW-timestamping/m-p/563064 Is there a way to make this work in DPDK? I'm honestly not sure what does it mean exactly "communicates directly with the controller", but I assume it has something to do with rte_eth_timesync_* ? I've actually tried already a test, I've executed rte_eth_timesync_enable/rte_eth_timesync_write_time and then verified with rte_eth_timesync_read_rx_timestamp if the timestamp is stored, and it seems it's there - but the packets are all coming with 0 in the timestamp field (mbuf)..
