  15 This hook loads the necessary modules for a network device.
  16 Detection will take place at runtime. To minimize the modules
  17 in the image, add the autodetect hook too.
  18 For pcmcia net devices please use pcmcia hook too.

  20 Kernel Parameters:
  21 An interface spec can be either short form, which is just the name of
  22 an interface (eth0 or whatever), or long form.  The long form consists
  23 of up to seven elements, separated by colons:
  24
  25 ip=<client-ip>:<server-ip>:<gw-ip>:<netmask>:<hostname>:<device>:<autoconf>
  26 nfsaddrs= is an alias to ip= and can be used too.
  27
  28 <client-ip>   IP address of the client. If empty, the address will
  29               either be determined by RARP/BOOTP/DHCP. What protocol
  30               is used de- pends on the <autoconf> parameter. If this
  31               parameter is not empty, autoconf will be used.
  32
  33 <server-ip>   IP address of the NFS server. If RARP is used to
  34               determine the client address and this parameter is NOT
  35               empty only replies from the specified server are
  36               accepted. To use different RARP and NFS server,
  37               specify your RARP server here (or leave it blank), and
  38               specify your NFS server in the 'nfsroot' parameter
  39               (see above). If this entry is blank the address of the
  40               server is used which answered the RARP/BOOTP/DHCP
  41               request.
  42
  43 <gw-ip>       IP address of a gateway if the server is on a different
  44               subnet. If this entry is empty no gateway is used and the
  45               server is assumed to be on the local network, unless a
  46               value has been received by BOOTP/DHCP.
  47
  48 <netmask>     Netmask for local network interface. If this is empty,
  49               the netmask is derived from the client IP address assuming
  50               classful addressing, unless overridden in BOOTP/DHCP reply.
  51
  52 <hostname>    Name of the client. If empty, the client IP address is
  53               used in ASCII notation, or the value received by
  54               BOOTP/DHCP.
  55
  56 <device>      Name of network device to use. If this is empty, all
  57               devices are used for RARP/BOOTP/DHCP requests, and the
  58               first one we receive a reply on is configured. If you
  59               have only one device, you can safely leave this blank.
  60
  61 <autoconf>    Method to use for autoconfiguration. If this is either
  62               'rarp', 'bootp', or 'dhcp' the specified protocol is
  63               used.  If the value is 'both', 'all' or empty, all
  64               protocols are used.  'off', 'static' or 'none' means
  65               no autoconfiguration.
  66 Examples:
  67 ip=127.0.0.1:::::lo:none  --> Enable the loopback interface.
  68 ip=192.168.1.1:::::eth2:none --> Enable static eth2 interface.
  69 ip=:::::eth0:dhcp --> Enable dhcp protcol for eth0 configuration.
  70
  71 nfsroot=[<server-ip>:]<root-dir>[,<nfs-options>]
  72
  73 If the 'nfsroot' parameter is NOT given on the command line, the default
  74 "/tftpboot/%s" will be used.
  75
  76 <server-ip>   Specifies the IP address of the NFS server. If this field
  77               is not given, the default address as determined by the
  78               'ip' variable (see below) is used. One use of this
  79               parameter is for example to allow using different servers
  80               for RARP and NFS. Usually you can leave this blank.
  81
  82 <root-dir>    Name of the directory on the server to mount as root. If
  83               there is a "%s" token in the string, the token will be
  84               replaced by the ASCII-representation of the client's IP
  85               address.
  86
  87 <nfs-options> Standard NFS options. All options are separated by commas.
  88               If the options field is not given, the following defaults
  89               will be used:
  90                       port            = as given by server portmap daemon
  91                       rsize           = 1024
  92                       wsize           = 1024
  93                       timeo           = 7
  94                       retrans         = 3
  95                       acregmin        = 3
  96                       acregmax        = 60
  97                       acdirmin        = 30
  98                       acdirmax        = 60
  99                       flags           = hard, nointr, noposix, cto, ac
 100
 101 root=/dev/nfs
 102
 103 If you don't use nfsroot= parameter you need to set root=/dev/nfs
 104 to boot from a nfs root by autoconfiguration.
