Hello everyone. I am trying to implement networking in Rust std using 
the TCP4 and TCP6 UEFI Protocols (It is required for running Rust CI 
tests). For providing the network device in qemu, I am using the 
following options:

```

-netdev user,id=net0,hostfwd=tcp::12345-:12345 -device 
virtio-net-pci,netdev=net0,mac=00:00:00:00:00:00

```

I am using these options since they are what are used by other Rust qemu 
targets. Anyway, the thing is, when I query for 
`EFI_TCP6_SERVICE_BINDING_PROTOCOL`, using the 
`BootServices->LocateHandle()` function, I get a buffer containing 8 
Handles.

Since I only supply one network device, I expected to get at-most 1 
device with this handle. So can anyone explain what is going on here? 
Can the same device publish the Service binding protocol multiple times?

Using `-net none` option gives 0 Handles, so that works how I would expect.


Yours Sincerely
