| 551 | help |
| 552 | This driver allows the kernel to act as a Xen network driver |
| 553 | domain which exports paravirtual network devices to other |
| 554 | Xen domains. These devices can be accessed by any operating |
| 555 | system that implements a compatible front end. |

| 557 | The corresponding Linux frontend driver is enabled by the |
| 558 | CONFIG_XEN_NETDEV_FRONTEND configuration option. |
| 559 | |
| 560 | The backend driver presents a standard network device |
| 561 | endpoint for each paravirtual network device to the driver |
| 562 | domain network stack. These can then be bridged or routed |
| 563 | etc in order to provide full network connectivity. |
| 564 | |
| 565 | If you are compiling a kernel to run in a Xen network driver |
| 566 | domain (often this is domain 0) you should say Y here. To |

| 608 | This provides an automated failover mechanism via APIs to create |
| 609 | and destroy a failover master netdev and manages a primary and |
| 610 | standby slave netdevs that get registered via the generic failover |
| 611 | infrastructure. This can be used by paravirtual drivers to enable |
| 612 | an alternate low latency datapath. It also enables live migration of |
| 613 | a VM with direct attached VF by failing over to the paravirtual |
| 614 | datapath when the VF is unplugged. |
