Hello all,
I want to measure the transmit latency in the host for a dpdk packet, so I need the timestamp before send (t1) and the hardware timestamp after the NIC finish sending the packet (t2). But I have some questions:
(1) How can I synchronizes the system clock to the hardware clock in the NIC binded to dpdk driver (like phc2sys in normal NIC driver)?
(2) How can I get the hardware timestamp t2?
Thank you for your time and consideration.
Sincerely, Zhang Xizhi
