Does DPDK provide RX timestamps?

Hi. I am using Intel (i210) and AWS ENA network interface cards.
I would like to measure the following RX latencies:
1) NIC to DPDK packet ring buffer
2) DPDK packet ring buffer to application via rte_eth_rx_burst.
I don't mind measuring in nanoseconds or CPU cycles.
Unfortunately I cannot find any mention of hardware timestamps.
I found brief references to mbuf containing a timestamp in the dynamic
fields, but nothing definitive.
Could someone please clarify what the situation is?
Thanks,
