NetAdapterStart fails with status 0xc0000001 #8

I followed the instructions and the RtEthSample code to implement a NetAdapter client in my WDF driver. The adapter is created successfully and I can see the corresponding network connection in the control panel.

The problem is that when I call NetAdapterStart from my EvtDevicePrepareHardware handler, it fails with status 0xc0000001.

Now, I'm not sure if I got everything correct when setting the adapter's capabilities using NetAdapterSetLinkLayerCapabilities and friends, so I left the stuff out where I'm unsure.

Therefore I wonder, are there any preconditions that must be met before calling NetAdapterStart other than passing a valid handle from NetAdapterCreate?

Calling NetAdapterSetDataPathCapabilities before NetAdapterStart solved my issue. Credits to @tylerretzlaff.
