UEFI TFTP/PXELINUX on thinkpad X230

[Thomas Lange]

I found a solution! Use syslinux.efi and ldlinux.e64 from experimental
The files can be found in those package versions

syslinux-common_6.04~git20171011.af7e95c3+dfsg1-3_all.deb
syslinux-efi_6.04~git20171011.af7e95c3+dfsg1-3_all.deb

Now UEFI netowrk boot works with my Thinkpad X230 with the new BIOS 2.73.
This means, there's no need for a loading a grubnetx64.efi and use
different config file for UEFI boot.

You can use the same configs in pxelinux.cfg/... created by
fai-chboot for PXE (legacy BIOS) and UEFI network boot.
