=Comment: #0================================================= Stephanie A. Glass <sglass@us.ibm.com> - 2007-09-19 12:09 EDT 1. Feature Id 201138 Feature Name Enhancing the active-backup mode of the Bonding driver. Sponsor PPC Category Device Drivers and IO Request Type Kernel - Enhancement from IBM 2. Short Description Add an option to the Bonding driver so that it could optionally failover on MAC addresses, rather than requiring all slaves to be with the same MAC address. 3. Describe the Business Case This enhancement is required in order to support bonding on top of the integrated Ethernet device (HEA) on all i/p6 systems and blades. Without this change, Bonding won't be working effectively, or won't be working at all (on Blades) on top of HEA. Any p6 customer who needs to rely on bonding for networking aggregation/failover will be affected if they intend it on HEA. Performance Assistance Required?: no Benefits: This enhancement is required in order to support bonding on top of networking devices which may not be handling multiple ports with the same MAC addresses as expected for the current bonding polling mechanisms. 4. Sponsor Priority: 1 IBM Confidential: no Code Contribution ?: IBM code Upstream Acceptance: In Progress Component Release Version Target: The patch is going to be submitted to kernel by 9/18 and is targetted to be included in kernel 2.6.24. Documentation Work: yes 5. Hardware to Red Hat: already available on site 6. PM Contact: Josh Poulson, jrp@us.ibm.com, 360-857-5053 7. Technical Contact: Jay Vosburgh, vosburgh@us.ibm.com, 425-954-4392
Created attachment 206271 [details] fail_over_mac option for bonding This patch adds a fail_over_mac option to bonding, to permit active-backup to function on devices that are displeased by having the MAC duplicated to all slaves. Patch against RHEL 2.6.18-43.el5 kernel.
Created attachment 210891 [details] TFD for feature TFD for this feature.
------- Comment From vosburgh@us.ibm.com 2007-10-16 14:29 EDT------- Bonding 'fail over mac' accepted into mainline.
Thanks, Jay. I'll try and get this added for the next update (5.2).
This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux maintenance release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Update release for currently deployed products. This request is not yet committed for inclusion in an Update release.
QE ack for RHEL5.2.
My test kernels have been updated to include a patch for this bugzilla. http://people.redhat.com/agospoda/#rhel5 Please test them and report back your results.
(In reply to comment #7) > My test kernels have been updated to include a patch for this bugzilla. Andy, Do you want this bz re-assigned to you ? I've built the attached patches attached here into my kernels (http://people.redhat.com/smoser/rhel5u2)
Sure thing, Scott. Sorry to steal your thunder on this one, but I did a big bonding update to 3.2.0 and this got added into the mix.

I gave the 2.6.18-58.el5.gtest.32 kernel a test drive, and it appears to function as expected (with regard to the fail_over_mac business).
This enhancement request was evaluated by the full Red Hat Enterprise Linux team for inclusion in a Red Hat Enterprise Linux minor release. As a result of this evaluation, Red Hat has tentatively approved inclusion of this feature in the next Red Hat Enterprise Linux Update minor release. While it is a goal to include this enhancement in the next minor release of Red Hat Enterprise Linux, the enhancement is not yet committed for inclusion in the next minor release pending the next phase of actual code integration and successful Red Hat and partner testing.
