What were you trying to do that didn't work?

Create and activate a "team" connection. Cockpit's tests create a "tteam" connection and try to bring it up, which fails in RHEL/CentOS 10.

I faintly remember some discussion about deprecating team devices (in favor of bonds?), but don't know the details. Is this even supposed to work in RHEL 10, or should NetworkManager-team be removed?

Please provide the package NVR for which bug is seen:

NetworkManager-1.47.4-1.el10.2.x86_64
NetworkManager-team-1.47.4-1.el10.2.x86_64
kernel-6.9.0-0.rc2.1.el10.x86_64

How reproducible: Always

Steps to reproduce

Start a team interface. If you need more details, I can cook up some nmcli invocation. Cockpit's tests use NM's D-Bus interface. But my first guess is that your integration tests already cover this, you just don't run them on RHEL/CentOS 10 yet?

Expected results

Either the device starts up, or team interfaces are not supported any more and thus NetworkManager-team should not exist.

Actual results

# nmcli c up tteam
Error: Connection activation failed: tteam failed to create resources: Failed to create team master interface 'tteam' for 'tteam': Operation not supported
