+This hook loads the necessary modules for a network device.
+Detection will take place at runtime. To minimize the modules
+in the image, add the autodetect hook too.
+For pcmcia net devices please use pcmcia hook too.
+
+Kernel Parameters:
+An interface spec can be either short form, which is just the name of
+an interface (eth0 or whatever), or long form. The long form consists
+of up to seven elements, separated by colons:
+
+ip=<client-ip>:<server-ip>:<gw-ip>:<netmask>:<hostname>:<device>:<autoconf>
+nfsaddrs= is an alias to ip= and can be used too.
+
+<client-ip> IP address of the client. If empty, the address will
+ either be determined by RARP/BOOTP/DHCP. What protocol
+ is used de- pends on the <autoconf> parameter. If this
+ parameter is not empty, autoconf will be used.
+
+<server-ip> IP address of the NFS server. If RARP is used to
+ determine the client address and this parameter is NOT
+ empty only replies from the specified server are
+ accepted. To use different RARP and NFS server,
+ specify your RARP server here (or leave it blank), and
+ specify your NFS server in the 'nfsroot' parameter
+ (see above). If this entry is blank the address of the
+ server is used which answered the RARP/BOOTP/DHCP
+ request.
+
+<gw-ip> IP address of a gateway if the server is on a different
+ subnet. If this entry is empty no gateway is used and the
+ server is assumed to be on the local network, unless a
+ value has been received by BOOTP/DHCP.
+
+<netmask> Netmask for local network interface. If this is empty,
+ the netmask is derived from the client IP address assuming
+ classful addressing, unless overridden in BOOTP/DHCP reply.
+
+<hostname> Name of the client. If empty, the client IP address is
+ used in ASCII notation, or the value received by
+ BOOTP/DHCP.
+
+<device> Name of network device to use. If this is empty, all
+ devices are used for RARP/BOOTP/DHCP requests, and the
+ first one we receive a reply on is configured. If you
+ have only one device, you can safely leave this blank.
+
+<autoconf> Method to use for autoconfiguration. If this is either
+ 'rarp', 'bootp', or 'dhcp' the specified protocol is
+ used. If the value is 'both', 'all' or empty, all
+ protocols are used. 'off', 'static' or 'none' means
+ no autoconfiguration.
+Examples:
+ip=127.0.0.1:::::lo:none --> Enable the loopback interface.
+ip=192.168.1.1:::::eth2:none --> Enable static eth2 interface.
+ip=:::::eth0:dhcp --> Enable dhcp protcol for eth0 configuration.
+
+nfsroot=[<server-ip>:]<root-dir>[,<nfs-options>]
+
+If the 'nfsroot' parameter is NOT given on the command line, the default
+"/tftpboot/%s" will be used.
+
+<server-ip> Specifies the IP address of the NFS server. If this field
+ is not given, the default address as determined by the
+ 'ip' variable (see below) is used. One use of this
+ parameter is for example to allow using different servers
+ for RARP and NFS. Usually you can leave this blank.
+
+<root-dir> Name of the directory on the server to mount as root. If
+ there is a "%s" token in the string, the token will be
+ replaced by the ASCII-representation of the client's IP
+ address.
+
+<nfs-options> Standard NFS options. All options are separated by commas.
+ If the options field is not given, the following defaults
+ will be used:
+ port = as given by server portmap daemon
+ rsize = 1024
+ wsize = 1024
+ timeo = 7
+ retrans = 3
+ acregmin = 3
+ acregmax = 60
+ acdirmin = 30
+ acdirmax = 60
+ flags = hard, nointr, noposix, cto, ac
+
+root=/dev/nfs
+
+If you don't use nfsroot= parameter you need to set root=/dev/nfs
+to boot from a nfs root by autoconfiguration.
