This needs the driver in the kernel, and Kernel Level IP config in the kernel.

You should see either the kernel parameter to be something with 'ip='
(so pxelinux actually gave this info to the kernel), see the driver initialize,
after this the kernel reporting it giving this IP to the driver. This all happens
before any initrd is used, so if you want to set it from an initrd you need to
get the IP address out of /proc/cmdline by yourself.

Regards,

Josef
