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 of problem:

For info upstream in https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/issues/509

In short, let's not default to generating connection profiles that attempt DHCP if there is a vlan device on top.

Version-Release number of selected component (if applicable):

NetworkManager-1.22.8-6.el8_2.x86_64

How reproducible:

Always

Steps to Reproduce:

See upstream bug

Actual results:

bond0 gets attempted for DHCP when there is a bond0.100. If bond0 can't get DHCP  then the VLAN device (bond0.100) gets taken down (see bz#1900038).

Expected results:

bond0 doesn't attempt DHCP or DHCP6

Additional info:

The upstream bug has been fixed upstream.
