efi_loader: Add network access support
We can now successfully boot EFI applications from disk, but users may want to also run them from a PXE setup. This patch implements rudimentary network support, allowing a payload to send and receive network packets. With this patch, I was able to successfully run grub2 with network access inside of QEMU's -M xlnx-ep108. Signed-off-by: Alexander Graf <agraf@suse.de>
