Not really; If you parse both "next server" from the last parsed packet (PxeReply) will overwrite the value gathered from the ProxyOffer and that leads to "Nest-server"= DHCP Server IP

This patch adds to Com32 modules the capabilities of accessing the EFI environment The idea is simple, the EFI parameters "image" and "table" received by syslinux.efi's efi_main() are stored in the "firmware" structure, next they are retrieved from the Com32 module which is linked against the gnu-efi static library. The Com32 module can use the EFI
