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.

Description David Hill 2016-08-31 20:32:14 UTC 
Description of problem:
ixgbe nic is falsely advertising MII support and is causing an error in OVS where failover won't behave as expected.

An ixgbe maintainer wrote a patch [1] and the OVS team is asking me to test this patch with the customer.  Would it be possible to merge this patch?

How reproducible:
Always

Steps to Reproduce:
1. Create a OVS bridge while bonding two ixgbe nics 
2. Unplug one of the cables
3. 

Actual results:
Failover is failing

Expected results:
Failover should work

We tested this patch and it's fixing our issue totally.
Comment 9 Ken Cox 2017-09-25 13:32:39 UTC 
David,

This patch has never made it upstream.  Can we get the customer's permission to open this bz to Intel so we can inquire?
Comment 10 David Hill 2017-09-25 14:54:52 UTC 
Hello sir,

  Why is this BZ private?  I think we can safely open it to the public.

Thank you very much,

David HIll
Comment 11 Ken Cox 2017-09-25 15:12:50 UTC 
Travis,

The patch mentioned in the description has not made it upstream yet.  This is reported to fix this bug for the customer.

Can we ping Intel and get status?

Reproduce this bug at kernel 3.10.0-327.el7.x86_64, close the physical switch port that connect to the ixgbe interface to simulate the unplug cable.
Verify it is be fixed at kernel 3.10.0-748.el7.x86_64.
