+- ``class`` [net|vdpa] (default **net**)
+
+  Choose the mode of operation of ef100 device.
+  **net** device will work as network device and will be probed by net/sfc driver.
+  **vdpa** device will work as vdpa device and will be probed by vdpa/sfc driver.
+  If this parameter is not specified then ef100 device will operate as

+
+- ``switch_mode`` [legacy|switchdev] (see below for default)
+
+  In legacy mode, NIC firmware provides Ethernet virtual bridging (EVB) API
+  to configure switching inside NIC to deliver traffic to physical (PF) and
+  virtual (VF) PCI functions. PF driver is responsible to build the
+  infrastructure for VFs, and traffic goes to/from VF by default in accordance
+  with MAC address assigned, permissions and filters installed by VF drivers.
+  In switchdev mode VF traffic goes via port representor (if any) on PF, and
+  software virtual switch (for example, Open vSwitch) makes the decision.
+  Software virtual switch may install MAE rules to pass established traffic
+  flows via hardware and offload software datapath as the result.
+  Default is legacy, unless representors are specified, in which case switchdev
+  is chosen.
+
+- ``representor`` parameter [list]
