ipxe provides efi drivers.  They are sitting in the PCI rom bar of the
qemu emulated nics and edk2 can use them just fine, on x86.  Right now
we support legacy bios, ia32 efi and x64 efi.

Now ipxe got arm and aarch64 support and the questions is whenever we
should add arm efi and/or aarch64 efi support to the nic pci roms.  I
somehow doubt it is that useful b/c I expect virtio-net being the only
relevant nic on arm virt and edk2 ships with a driver for virtio-net, so
it works fine without the ipxe driver in the rom.

hope this clarifies,
