+Bridge offload
+==============
+The mlx5 driver implements support for offloading bridge rules when in switchdev
+mode. Linux bridge FDBs are automatically offloaded when mlx5 switchdev
+representor is attached to bridge.
+
+- Change device to switchdev mode::
+
+    $ devlink dev eswitch set pci/0000:06:00.0 mode switchdev
+
+- Attach mlx5 switchdev representor 'enp8s0f0' to bridge netdev 'bridge1'::
+
+    $ ip link set enp8s0f0 master bridge1
