RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

How reproducible: Reproducible


Steps to Reproduce: 
1. Configure OVS-dpdk on two Synergy servers
2. Add QEDE as a dpdk interface to each OVS-dpdk bridge
3. Add int0 as an internal port to each OVS-dpdk bridge
4. Ping should fail

Actual results:

Comment 2 Jean-Tsung Hsiao 2018-12-08 16:30:58 UTC 
NOTE: OVS-kernel case is working. Switch fabric configuration could be an issue here based on OVS-dpdk over Cisco UCS experience.
Comment 3 qding 2018-12-10 07:05:36 UTC 
When qede port running DPDK, all packets received on the port will have QinQ header and packets sent out from the port cannot be seen on the peer which may be filtered by switch in between.

Please see log below, the only change between the two test is qede port running as kernel interface or dpdk

1. When qede port added to ovs bridge as kernel interface
