[Test Setup]
Steps to reproduce
List the steps to reproduce the issue.
1. Bind 2 CBDMA channels to vfio-pci:
dpdk-devbind.py --force --bind=vfio-pci 0000:80:04.0 0000:80:04.1
2. Start vhost-tetpmd:
x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 28-36 -n 4 -a 0000:80:04.0 -a
0000:80:04.1 --file-prefix=vhost_247798_20220628141037 --vdev
'net_vhost0,iface=vhost-net0,queues=1,tso=1,dmas=[txq0;rxq0]' --vdev
'net_vhost1,iface=vhost-net1,queues=1,tso=1,dmas=[txq0;rxq0]' --iova=va -- -i
--nb-cores=2 --txd=1024 --rxd=1024 --txq=1 --rxq=1
--lcore-dma=[lcore29@0000:80:04.0,lcore30@0000:80:04.1]
start
3. Start VM0:
taskset -c 20,21,22,23,24,25,26,27 /home/QEMU/qemu-7.0.0/bin/qemu-system-x86_64
-name vm0 -enable-kvm -pidfile /tmp/.vm0.pid -daemonize -monitor

5. SSH login VM0 and VM1 to config IP:
[VM0]
ssh root@10.239.252.220 -p 6000
ifconfig ens4 1.1.1.1
[VM1]
ssh root@10.239.252.220 -p 6001
ifconfig ens4 1.1.1.2
6. Use iperf test tool to test between 2 VMs
[VM0]
iperf -s -i 1
[VM1]
iperf -c 1.1.1.1 -i 1 -t 60
Show the output from the previous commands.
There is no any data.
[Expected Result]
Explain what is the expected result in text or as an example output:

net/vhost: enable compliant offloading mode
This patch enables the compliant offloading flags mode by
default, which prevents the Rx path to set Tx offload flags,
which is illegal. A new legacy-ol-flags devarg is introduced
to enable the legacy behaviour.
