Add new device generic parameter to enable/disable creation of VDPA net auxiliary device and associated device functionality in the devlink instance. User who prefers to disable such functionality can disable it using below example. $ devlink dev param set pci/0000:06:00.0 \ name enable_vnet value false cmode driverinit $ devlink dev reload pci/0000:06:00.0 At this point devlink instance do not create auxiliary device for the VDPA net functionality.
