[syslinux] syslinux.efi pxeboot across multiple subnets

[Jason Matthews]

I don't really know what I'm doing, but I was playing around in efi/udp.c
and noticed that the gateway is being set to NULL. I changed:

txdata->GatewayAddress = NULL;

to

txdata->GatewayAddress = &IPInfo.gateway;

After that change, I see ldlinux.e64 attempt to download and connect to my
tftpserver, but it never completes and gets stuck in a loop.
