Andrei Borzenkov c52ae40570 efinet: skip virtual IPv4 and IPv6 devices when enumerating cards 
EDK2 PXE driver creates two child devices - IPv4 and IPv6 - with
bound SNP instance. This means we get three cards for every physical
adapter when enumerating. Not only is this confusing, this may result
in grub ignoring packets that come in via the "wrong" card.

Example of device hierarchy is

 Ctrl[91] PciRoot(0x0)/Pci(0x3,0x0)
   Ctrl[95] PciRoot(0x0)/Pci(0x3,0x0)/MAC(525400123456,0x1)
     Ctrl[B4] PciRoot(0x0)/Pci(0x3,0x0)/MAC(525400123456,0x1)/IPv4(0.0.0.0)
     Ctrl[BC] PciRoot(0x0)/Pci(0x3,0x0)/MAC(525400123456,0x1)/IPv6(0000:0000:0000:0000:0000:0000:0000:0000)

Skip PXE created virtual devices when enumerating cards. Make sure to
find real card when applying initial autoconfiguration during PXE boot,
this information is associated with one of child devices.
