Device emulations in VirtualBox - especially if they need to do ioctls -
are regular user level programs. And since ioctls are by definition
completely specific to the host OS and the driver in question there is
no IPRT support for this. But as your device is inherently OS specific
there's probably nothing wrong with just doing the ioctls you need.
May I ask what kind of network interface this is? Because many network
interfaces can be used through the existing networking support.
