With Linux Bridge Switchdev, certain +networking functions like forwarding, filtering, and learning of Ethernet +frames can be offloaded to a hardware switch. This offloading reduces the +burden on the Linux kernel and CPU, leading to improved network performance +and lower latency. + +To use Linux Bridge Switchdev, you need hardware switches that support the +switchdev interface. This means that the switch hardware needs to have the +necessary drivers and functionality to work in conjunction with the Linux +kernel. + +Please see the :ref:`switchdev` document for more details. + FAQ === |
