+Hardware offload extension
+==========================
+
+The ``port-hardware-offload`` extension adds ``hardware_offload_type``
+attribute to the port resource. This attribute stores the type of hardware
+offload the port is going to use and will be populated in the port binding
+profile information with "'capabilities': [<hardware_offload_type>]".
