Hello,

I am trying to set up dpdk with netvsc as master pmd on Azure following
https://learn.microsoft.com/en-us/azure/virtual-network/s=
etup-dpdk?tabs=3Dubuntu
and
https://doc.=
dpdk.org/guides-22.11/nics/netvsc.html.

On the Azure VM, I have a LAN and a WAN interface with accelerated net=
working enabled.I have unbound both the VMBUS devices from the kernel and b=
ound it to uio_hv_generic.The DPDK version is 22.11 running on openwrt 5.15=
.150.
When I try running testpmd=
 in io mode to send and receive traffic between LAN and WAN port, I notice =
very low throughput.  Please find the testpmd command and stats below:

If I try with 2 queues , the throughput only slightly improves. =
I expected to see larger values.
After=
 enabling debug logs i observe that
1.=
 Both the VMbus devices are being probed and matching VF devices found
2. VF devices are being configured with Rx=
 and Tx queue setup.
Any ideas what I might be doing wrong?
