  11           any other computer at all.
  12
  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.

  46           Channels together. This is called 'Etherchannel' by Cisco,

  65           If you use SLIP or PPP, you might want to say Y here. It won't
  66           enlarge your kernel. What a deal. Read about it in the Network

  78           SLIP (the protocol for sending Internet traffic over telephone
  79           lines) or PPP (a better SLIP) on them, you can make them behave like
  80           one double speed connection using this driver.  Naturally, this has
  81           to be supported at the other end as well, either with a similar EQL
  82           Linux driver or with a Livingston Portmaster 2e.

 450           This driver allows the kernel to act as a Xen network driver
 451           domain which exports paravirtual network devices to other
 452           Xen domains. These devices can be accessed by any operating
 453           system that implements a compatible front end.

 458           The backend driver presents a standard network device
 459           endpoint for each paravirtual network device to the driver
 460           domain network stack. These can then be bridged or routed
 461           etc in order to provide full network connectivity.

 463           If you are compiling a kernel to run in a Xen network driver
 464           domain (often this is domain 0) you should say Y here. To
