*NetworkManager* now supports ordering bond slaves based on device names
Previously, the existing order of activation for slave connections could cause problems determining the MAC address of the master interface. This update adds more predictable ordering based on device names. You can enable the new ordering using the `slaves-order=name` setting in *NetworkManager* configuration.
Note that the new ordering is disabled by default and must be explicitly enabled.

Description

This is a major issue on bond usage in Cockpit in the RHV hypervisor. Can we propose this to z stream? Pushed upstream branch bg/slaves-order-rh1420708 for review. The branch LGTM *** Bug 1387506 has been marked as a duplicate of this bug. *** (In reply to Beniamino Galvani from comment #4) > Pushed upstream branch bg/slaves-order-rh1420708 for review. lgtm As stated here [1], initscripts simply ignore interfaces that appear too late in the boot process and thus any late slave device will not even be activated. NM works better in this situation because it activates the slave when it appears, but of course it can't guarantee the order of activation. For such corner cases, the suggested solution is to set a fixed MAC address on the bond. To wrap this up, I would merge bg/slaves-order-rh1420708 so that at least we have an activation order consistent with initscripts in most of the cases.

(In reply to Yaniv Dary from comment #18) > Can you please clone this one? Do you want this to be cloned for 7.3.z? As stated in comment 5 and comment 8, we don't think this change is suitable for z-stream inclusion.
