You can try it with testpmd as following: port stop all port config all rx-timestamp on port start all start
you will get all packets as following if running in rxonly mode. port 1/queue 1: received 1 packets src=00:16:3E:23:D0:6D - dst=7C:FE:90:12:23:15 - type=0x8100 - length=1496 - nb_segs=1 - RSS hash=0xf32d0b79 - RSS queue=0x1 - timestamp 189810534625590 - hw ptype: L2_ETHER L3_IPV4_EXT_UNKNOWN L4_NONFRAG - sw ptype: L2_ETHER_VLAN L3_IPV4 - l2_len=18 - l3_len=20 - Receive queue=0x1 ol_flags: PKT_RX_RSS_HASH PKT_RX_L4_CKSUM_UNKNOWN PKT_RX_IP_CKSUM_UNKNOWN PKT_RX_TIMESTAMP Kindest regards, Raslan Darawsheh -----Original Message----- From: users [mailto:users-boun...@dpdk.org] On Behalf Of Yuliang Li Sent: Monday, July 9, 2018 6:56 PM To: users@dpdk.org Subject: [dpdk-users] NIC rx timestamp Hi, Is there any way to get the NIC (hardware) rx timestamp for every packet in dpdk?
