.. cfgcmd:: set interface ethernet <interface> switchdev

Switches this interface to `switchdev` mode that allows network interfaces to offload
certain networking functions directly to hardware, like a network switch or a SmartNIC.
This enables higher performance and lower latency for network processing by
bypassing the kernel's network stack for supported operations.

.. note:: This is only supported on certain physical network interfaces
and depends on specific models and drivers.
