What kind of nic do you have? Can you capture "show hardw" ?

Hi,
I configured 2 worker thread and 2 dpdk rx-queuein startup.conf . Then I
forged 400w packets and send them to a single dpdk interface . It turns out
that the second thread received only 24 packets .I test it for several times
and the results are almost the same. Why did this happen ?
Here is some config and "show":
VPP : 18.07
startup.conf:
cpu {
main-core 1
corelist-workers 2,3
}
dpdk {
dev default {
num-rx-queues 2
num-tx-queues 2
}
}
packets:
these pkts share the same src mac , dst mac and ipv4 body , only ipv4 src ip
and dst ip are different from each other.
