You seem to be ignoring what I am telling you.


* Your custom UEFI driver stack has the incorrect hierarchy of handles.

* Your SNP driver should bind to a hardware device handle and then 
install EFI_SIMPLE_NETWORK_PROTOCOL onto a new handle.

You must first fix your own SNP driver as I have described.

Your SNP driver will then work with iPXE as expected, without any hacks 
such as skipping the call to bs->DisconnectController.
