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

I was looking at the source code but I'm more OOP C++ than C. I found eth_ena_recv_pkts but is it possible for me to add a software timestamp before the mbuf is added to the ring buffer? This would be incredibly useful. On Mon, 9 Sept 2024 at 09:31, Brandes, Shai wrote: > > > >
