[PATCH] display bootserver in /proc/net/pnp

From: "lode leroy" <lode_leroy@hotmail.com>

I would like to submit a trivial enhancement to display the ip address of
the bootserver in /proc/net/pnp

This aids me in developing a diskless linux root image to know where it
comes from...

net/ipv4/ipconfig.c
