++ depends on BKL # unfixable, just use autofs4
+ help
+ The automounter is a tool to automatically mount remote file systems
+ on demand. This implementation is partially kernel-based to reduce
+ overhead in the already-mounted case; this is unlike the BSD
+ automounter (amd), which is a pure user space daemon.
+
+ To use the automounter you need the user-space tools from the autofs
+ package; you can find the location in <file:Documentation/Changes>.
+ You also want to answer Y to "NFS file system support", below.
+
+ If you want to use the newer version of the automounter with more
+ features, say N here and say Y to "Kernel automounter v4 support",
+ below.
+
+ To compile this support as a module, choose M here: the module will be
+ called autofs.
+
+ If you are not a part of a fairly large, distributed network, you
+ probably do not need an automounter, and can say N here.

+ select NLS
+ help
+ SMB (Server Message Block) is the protocol Windows for Workgroups
+ (WfW), Windows 95/98, Windows NT and OS/2 Lan Manager use to share
+ files and printers over local networks. Saying Y here allows you to
+ mount their file systems (often called "shares" in this context) and
+ access them just like any other Unix directory. Currently, this
+ works only if the Windows machines use TCP/IP as the underlying
+ transport protocol, and not NetBEUI. For details, read
+ <file:Documentation/filesystems/smbfs.txt> and the SMB-HOWTO,
+ available from <http://www.tldp.org/docs.html#howto>.
+
+ Note: if you just want your box to act as an SMB *server* and make
+ files and printing services available to Windows clients (which need
+ to have a TCP/IP stack), you don't need to say Y here; you can use
+ the program SAMBA (available from <ftp://ftp.samba.org/pub/samba/>)
+ for that.
+
+ General information about how to connect Linux, Windows machines and
+ Macs is on the WWW at <http://www.eats.com/linux_mac_win.html>.
+
+ To compile the SMB support as a module, choose M here:
+ the module will be called smbfs. Most people say N, however.
+
+ config SMB_NLS_DEFAULT
+ bool "Use a default NLS"
+ depends on SMB_FS
+ help
+ Enabling this will make smbfs use nls translations by default. You
+ need to specify the local charset (CONFIG_NLS_DEFAULT) in the nls
+ settings and you need to give the default nls for the SMB server as
+ CONFIG_SMB_NLS_REMOTE.
+
+ The nls settings can be changed at mount time, if your smbmount
+ supports that, using the codepage and iocharset parameters.
+
+ smbmount from samba 2.2.0 or later supports this.
+
+ config SMB_NLS_REMOTE
+ string "Default Remote NLS Option"
+ depends on SMB_NLS_DEFAULT
+ default "cp437"
+ help
+ This setting allows you to specify a default value for which
+ codepage the server uses. If this field is left blank no
+ translations will be done by default. The local codepage/charset
+ default to CONFIG_NLS_DEFAULT.
+
+ The nls settings can be changed at mount time, if your smbmount
+ supports that, using the codepage and iocharset parameters.

- *
- * DESCRIPTION:
- *
- * wl_insert() is scheduled to run after a CARD_INSERTION event is
- * received, to configure the PCMCIA socket, and to make the ethernet device
- * available to the system.
- *
- * PARAMETERS:
- *
- * dev - a pointer to the net_device struct of the wireless device
- *
- * RETURNS:
- *
- * TRUE or FALSE
