cifs: update cifs.txt and remove some outdated infos

  This is the client VFS module for the Common Internet File System

  (CIFS) protocol which is the successor to the Server Message Block 

  (SMB) protocol, the native file sharing mechanism for most early

  PC operating systems.  CIFS is fully supported by current network

  file servers such as Windows 2000, Windows 2003 (including  

  Windows XP) as well by Samba (which provides excellent CIFS

  PC operating systems. New and improved versions of CIFS are now

  called SMB2 and SMB3. These dialects are also supported by the

  CIFS VFS module. CIFS is fully supported by network

  file servers such as Windows 2000, 2003, 2008 and 2012

  as well by Samba (which provides excellent CIFS

  server support for Linux and many other operating systems), so

  this network filesystem client can mount to a wide variety of

  servers.  The smbfs module should be used instead of this cifs module

  for mounting to older SMB servers such as OS/2.  The smbfs and cifs

  modules can coexist and do not conflict.  The CIFS VFS filesystem

  module is designed to work well with servers that implement the

  newer versions (dialects) of the SMB/CIFS protocol such as Samba, 

  the program written by Andrew Tridgell that turns any Unix host 

  into a SMB/CIFS file server.

  servers.

  The intent of this module is to provide the most advanced network

  file system function for CIFS compliant servers, including better

  alternative to NFSv4 for fileserving in some Linux to Linux environments,

  not just in Linux to Windows environments.

  This filesystem has an optional mount utility (mount.cifs) that can

  be obtained from the project page and installed in the path in the same

  directory with the other mount helpers (such as mount.smbfs). 

  Mounting using the cifs filesystem without installing the mount helper

  requires specifying the server's ip address.

  This filesystem has an mount utility (mount.cifs) that can be obtained from

  For Linux 2.4:

    mount //anything/here /mnt_target -o

            user=username,pass=password,unc=//ip_address_of_server/sharename

      https://ftp.samba.org/pub/linux-cifs/cifs-utils/

  For Linux 2.5: 

    mount //ip_address_of_server/sharename /mnt_target -o user=username, pass=password

  It must be installed in the directory with the other mount helpers.
