The NIC is intel 82576 Gigabit NIC. The Version of pktgen is 3.5.2. The Version of dpdk is 17.11.2.
I also try another way. I use two ports on both sides of machines.On the machine A , run pktgen with the command “./pktgen –c 0xf –n2 -- -P –m “2.0,3.1””. And on the machine B ,run dpdk with the command “./test_pmd –c 0xf –n2 -- -i –portmask=0x3 –coremask=0xc”. It can also only send a few packets and stop.
