+Linux Bridge Switchdev is a feature in the Linux kernel that extends the
+capabilities of the traditional Linux bridge to work more efficiently with
+hardware switches that support switchdev. 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
+Please see the :ref:`switchdev` document for more details.
