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

Ian Campbellf942dc22011-03-15 00:06:18 +0000378 This driver provides support for Xen paravirtual network
379 devices exported by a Xen network driver domain (often
380 domain 0).
381
382 The corresponding Linux backend driver is enabled by the
383 CONFIG_XEN_NETDEV_BACKEND option.
384
385 If you are compiling a kernel for use as Xen guest, you
386 should say Y here. To compile this driver as a module, chose
387 M here: the module will be called xen-netfront.

392 help
393 This driver allows the kernel to act as a Xen network driver
394 domain which exports paravirtual network devices to other
395 Xen domains. These devices can be accessed by any operating
396 system that implements a compatible front end.
397
398 The corresponding Linux frontend driver is enabled by the
399 CONFIG_XEN_NETDEV_FRONTEND configuration option.
400
401 The backend driver presents a standard network device
402 endpoint for each paravirtual network device to the driver
403 domain network stack. These can then be bridged or routed
404 etc in order to provide full network connectivity.
405
406 If you are compiling a kernel to run in a Xen network driver
407 domain (often this is domain 0) you should say Y here. To
408 compile this driver as a module, chose M here: the module
409 will be called xen-netback.
