You can say N here if you don't intend to connect your Linux box to
|
|
any other computer at all.

You'll have to say Y if your computer contains a network card that
|

you want to use under Linux. If you are going to run SLIP or PPP over

telephone line or null modem cable you need say Y here. Connecting

two machines with parallel ports using PLIP needs this, as well as

WireGuard is a secure, fast, and easy to use replacement for IPSec

designed to be fairly general purpose and abstract enough to fit most

configure. See www.wireguard.com for more info.

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

This provides an automated failover mechanism via APIs to create
|
|
and destroy a failover master netdev and manages a primary and
|
|
standby slave netdevs that get registered via the generic failover
|
|
infrastructure. This can be used by paravirtual drivers to enable
|
|
an alternate low latency datapath. It also enables live migration of

a VM with direct attached VF by failing over to the paravirtual
|
|
datapath when the VF is unplugged.
