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: [email protected]
Reporter: [email protected]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.
