+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.
