            Bug ID: 1534
           Summary: Transmit errors with iavf VF using SR-IOV on VM
           Product: DPDK
           Version: 24.07
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: ethdev
          Assignee: dev at dpdk.org
          Reporter: Junya.Oda at anritsu.com
  Target Milestone: ---

Overview:
I have created an application based on “examples/l2fwd”.
There is a problem that unable to transmit any packets.
(Receiving packets is working)

It seems similar to the following bug:
https://bugs.dpdk.org/show_bug.cgi?id=590

Steps to Reproduce:
1. Create SR-IOV VF on Hypervisor
2. Create VM with SR-IOV-Passthrough 
3. Bind "igb_uio" to VF
4. Launch software

At step2, VF can communicate a external switch

Actual Results:
No packets are transmitted.

When "rte_eth_stats_get" is executed,
“oerrors” matched the number of packets that were attempted to be sent.

Expected Results:
The packets should be transmitted.
