10 | You can say N here if you don't intend to connect your Linux box to | |
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. | |

437 | This driver provides support for Xen paravirtual network |
438 | devices exported by a Xen network driver domain (often | |
439 | domain 0). | |
440 | ||
441 | The corresponding Linux backend driver is enabled by the | |
442 | CONFIG_XEN_NETDEV_BACKEND option. | |
443 | ||
444 | If you are compiling a kernel for use as Xen guest, you | |
445 | should say Y here. To compile this driver as a module, chose | |
446 | M here: the module will be called xen-netfront. | |

451 | help | |
452 | This driver allows the kernel to act as a Xen network driver | |
453 | domain which exports paravirtual network devices to other | |
454 | Xen domains. These devices can be accessed by any operating | |
455 | system that implements a compatible front end. | |
456 | ||
457 | The corresponding Linux frontend driver is enabled by the | |
458 | CONFIG_XEN_NETDEV_FRONTEND configuration option. | |
459 | ||
460 | The backend driver presents a standard network device | |
461 | endpoint for each paravirtual network device to the driver | |
462 | domain network stack. These can then be bridged or routed | |
463 | etc in order to provide full network connectivity. | |
464 | ||
465 | If you are compiling a kernel to run in a Xen network driver | |
466 | domain (often this is domain 0) you should say Y here. To | |
467 | compile this driver as a module, chose M here: the module | |
468 | will be called xen-netback. | |

517 | help | |
518 | This provides an automated failover mechanism via APIs to create | |
519 | and destroy a failover master netdev and manages a primary and | |
520 | standby slave netdevs that get registered via the generic failover | |
521 | infrastructure. This can be used by paravirtual drivers to enable | |
9437b629 | 522 | an alternate low latency datapath. It also enables live migration of |
cfc80d9a SS |
523 | a VM with direct attached VF by failing over to the paravirtual |
524 | datapath when the VF is unplugged. | |
