 Hi:
  
 I have a question about the dpdk bond.  My Openstack vm use 4 vfs support by SR-IOV. And i can not start dpdk-testpmd with dpdk bond mode 1. The error is "i40evf_dev_tx_queue_start(): Failed to switch TX queue 0 on".

 My host environment is:
 Two Intel x710 NIC, and slicing each NIC to 16 vfs. My VM use 4 vfs like this:
 [root@overcloud-computelowconfig-0 ~]# ip link show ens2f0
 8: ens2f0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000

[root@overcloud-computelowconfig-0 ~]# ip link show ens2f1

    vf 12     link/ether fa:16:3e:bc:9a:2f brd ff:ff:ff:ff:ff:ff, vlan 362, spoof checking off, link-state enable, trust off

    vf 14     link/ether fa:16:3e:63:4b:e9 brd ff:ff:ff:ff:ff:ff, vlan 361, spoof checking off, link-state enable, trust off

My vm environment is:
DPDK version dpdk-21.02.
[root@sriovtest-upf-42-gsu-0 app]# dpdk_nic_bind.py --status

So, how can i fix this error?  

I look forward to hearing from you soon.
