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.
+
+ 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
