SourceHandle of NetBufferList is set to NULL by vmxnet3.sys, which causes abnormal behavior..

[#1]

Please understand that my English is not good before starting...

I installed Windows 2019 server on VMWare Workstation.

And I found that there is an critical issue(maybe..?) where the network function is malfunctioning.

The cause is VMWare's vmxnet3.sys driver.

Look at the picture below..

The current state of the WFP layer is FWPM_LAYER_INBOUND_MAC_FRAME_ETHERNET.

The SourceHandle in NBL is NULL.

That is, the NIC information of the packet received from vmxnet3.sys cannot be obtained.

So I am requesting a review of the fix for this bug.

Thanks

Thanks for reporting this!  I have passed your request to our vmxnet3 driver people, and they should be able to either address the issue or respond here with an explanation.
