EFI equivalent of undionly.kpxe

[NiKiZe]

As I understand the DHCP packets is not cached in EFI and thus not available for iPXE to read, and therefore it needs to do a full dhcp to get the information. Hopefully mcb30 can jump in here and give the correct explanation.

EFI and legacy iPXE load is fundamentaly different, for example ipxe.efi can load its own native drivers and fallback to NII or SNP if there is no native driver available, this is a big difference from legacy ipxe where there is no support for native and undi in the same binary.
