I have tried to get hw timestamps of packets on Intel X550T(10G) and
AQC107(10G).
But RTE_ETH_RX_OFFLOAD_TIMESTAMP = 0 in dev_info.rx_offload_capa.
Tell me is it possible to get hw timestamps on these NICs with DPDK?
Which 10G NICs support this option?

Looking at the doc, and the code, none of those drivers (net/ixgbe,
net/atlantic) seem to support this feature.
I'll let the maintainers reply on the feasibility.

The documentation from the main repository provides a list of per
driver features:
https://doc.dpdk.org/guides/nics/overview.html
For an already released DPDK, the link becomes
https://doc.dpdk.org/guides-<version>/nics/overview.html.
Like, for example: https://doc.dpdk.org/guides-22.11/nics/overview.html
