  10          You can say N here if you don't intend to connect your Linux box to
  11          any other computer at all.
  13          You'll have to say Y if your computer contains a network card that
  14          you want to use under Linux. If you are going to run SLIP or PPP over
  15          telephone line or null modem cable you need say Y here. Connecting
  16          two machines with parallel ports using PLIP needs this, as well as
  17          AX.25/KISS for sending Internet traffic over amateur radio links.

  42          Say 'Y' or 'M' if you wish to be able to 'bond' multiple Ethernet
  43          Channels together. This is called 'Etherchannel' by Cisco,
  44          'Trunking' by Sun, 802.3ad by the IEEE, and 'Bonding' in Linux.
  46          The driver supports multiple bonding modes to allow for both high
  47          performance and high availability operation.
  49          Refer to <file:Documentation/networking/bonding.txt> for more
  50          information.
  52          To compile this driver as a module, choose M here: the module

  58          This is essentially a bit-bucket device (i.e. traffic you send to
  59          this device is consigned into oblivion) with a configurable IP
  60          address. It is most commonly used in order to make your currently
  61          inactive SLIP address seem like a real address for local programs.
  62          If you use SLIP or PPP, you might want to say Y here. Since this
  63          thing often comes in handy, the default is Y. It won't enlarge your
  64          kernel either. What a deal. Read about it in the Network
  65          Administrator's Guide, available from

  74          If you have two serial connections to some other computer (this
  75          usually requires two modems and two telephone lines) and you use
  76          SLIP (the protocol for sending Internet traffic over telephone
  77          lines) or PPP (a better SLIP) on them, you can make them behave like
  78          one double speed connection using this driver.  Naturally, this has
  79          to be supported at the other end as well, either with a similar EQL
  80          Linux driver or with a Livingston Portmaster 2e.
  82          Say Y if you want this and read
  83          <file:Documentation/networking/eql.txt>.  You may also want to read
  84          section 6.2 of the NET-3-HOWTO, available from
  85          <>.

  94          Fibre Channel is a high speed serial protocol mainly used to connect
  95          large storage devices to the computer; it is compatible with and
  96          intended to replace SCSI.
  98          If you intend to use Fibre Channel, you need to have a Fibre channel
  99          adaptor card in your computer; say Y here and to the driver for your
 100          adaptor below. You also should have said Y to "SCSI support" and
 101          "SCSI generic support".

 202          receives them from user space program and instead of sending packets
 203          via physical media writes them to the user space program.
 205          When a program opens /dev/net/tun, driver creates and registers
 206          corresponding net device tunX or tapX.  After a program closed above
