Macro register_ibv_device_impl 

macro_rules! register_ibv_device_impl {
    ($impl_ty:ty) => { ... };
}

Submits an inventory entry for a concrete IbvDeviceImpl.

Place one invocation per impl at module scope. The expansion references inventory and typeuri by bare crate name, so the calling crate must list both as direct dependencies.

register_ibv_device_impl!(StandardImpl);
