* Decode any IP configuration options in the "ip=" or "nfsaddrs=" kernel

- *
- * Any of the fields can be empty which means to use a default value:
- * <client-ip> - address given by BOOTP or RARP
- * <server-ip> - address of host returning BOOTP or RARP packet
- * <gw-ip> - none, or the address returned by BOOTP
- * <netmask> - automatically determined from <client-ip>, or the
- * one returned by BOOTP
- * <host name> - <client-ip> in ASCII notation, or the name returned
- * by BOOTP
- * <device> - use all available devices
- * <PROTO>:
- * off|none - don't do autoconfig at all (DEFAULT)
- * on|any - use any configured protocol
- * dhcp|bootp|rarp - use only the specified protocol
- * both - use both BOOTP and RARP (not DHCP)
