OK.  We want to be driving handle 0x68ffa518.  We need to disconnect 
MNPSb etc, so that we can gain control of the network device.

However, the SNP instance (0x691df020) is being exposed via both 
handles.  I'm not sure what logic we could sensibly apply in order to 
obtain the first handle as our designated handle.

What happens if you try to load snp.efi (instead of snponly.efi) on this 
system?
