NetworkManager Bridging Support

Summary

NetworkManager should be able to configure bridging interfaces consisting of wired and wireless ethernet devices. It should be able to fulfill server and virtualization bridging usecases.

Detailed Description

Bridging is about connecting 2 or more network devices to make network traffic automatically go from the one to the other. The network devices can be physical or virtual.

Bridging is a commonly used technology to connect VMs to the outside world: create a tap device on the host, create a bridge between the physical nic and the tap, let the vm use the tap device as its nic. So far, this setup is handled by libvirt. This is the main driving use case for this feature.

Bonding is about glueing two network connections together and treat them as a single connection with bigger bandwidth. This happens at the ethernet level and thus only works if the two connections are to the same network. Bonding has uses mainly on servers, and is more of a byproduct in this feature, since the infrastructure for bridging will likely also support bonding.

Benefit to Fedora

NetworkManager becomes a more central point for network configuration, giving a more unified user experience. Virtualization on Fedora will be easier to set up.

Scope

This feature requires changes to NetworkManager, nm-applet, nm-connection-editor, gnome-shell, gnome-control-center and KDE counterparts.

How To Test

TBD

User Experience

TBD

Dependencies

libvirt may need to be adapted. See also Features/Shared_Network_Interface.

Contingency Plan

Don't support bridging in NetworkManager, virtualization will continue to rely on libvirt for this purpose.

Documentation

TBD

Release Notes

TBD
