Steps to reproduce
1. Boot a guest with 4 nics(name: vm1)
-device '{"id": "pcie-root-port-3", "port": 3, "driver": "pcie-root-port", "addr": "0x1.0x3", "bus": "pcie.0", "chassis": 4}' \
-device '{"driver": "virtio-net-pci", "mac": "9a:6c:e7:f9:0a:f6", "id": "idxjU8xC", "netdev": "id7wOdjI", "bus": "pcie-root-port-3", "addr": "0x0"}' \
-netdev '{"id": "id7wOdjI", "type": "tap", "fd": "14"}' \
-device '{"id": "pcie-root-port-4", "port": 4, "driver": "pcie-root-port", "addr": "0x1.0x4", "bus": "pcie.0", "chassis": 5}' \
-device '{"driver": "e1000e", "mac": "9a:6c:e7:f9:0a:f7", "id": "idRGSMoo", "netdev": "idajNVB0", "bus": "pcie-root-port-4", "addr": "0x0"}' \

-device '{"driver": "e1000e", "mac": "9a:6c:e7:f9:0a:f9", "id": "idY6ozrV", "netdev": "id7q1368", "bus": "pcie-root-port-6", "addr": "0x0"}' \
-netdev '{"id": "id7q1368", "type": "tap", "fd": "18"}
2.Boot another 4 client guests
3.Stop firewall for all guests
systemctl stop firewalld.service
4. Config static route in vm1
route add -host 10.72.138.108 eth0
route add -host 10.72.139.36 eth1
route add -host 10.72.138.210 eth2
route add -host 10.72.139.19 eth3
5.Launch netperf server on the another 4 guests.
/var/tmp/netperf-2.7.1/src/netserver
6.Launch 4 clients in parallal in vm1
/var/tmp/netperf-2.7.1/src/netperf -H 10.72.138.108 -t UDP_STREAM -l 60 – -m 1500 > /dev/null & /var/tmp/netperf-2.7.1/src/netperf -H 10.72.139.36 -t UDP_STREAM -l 60 – -m 1500 > /dev/null & /var/tmp/netperf-2.7.1/src/netperf -H 10.72.138.210 -t UDP_STREAM -l 60 – -m 1500 > /dev/null & /var/tmp/netperf-2.7.1/src/netperf -H 10.72.139.19 -t UDP_STREAM -l 60 – -m 1500 > /dev/null &
Expected results
Test pass and there are no any error messages
