10 You can say N here if you don't intend to connect your Linux box to
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
17 AX.25/KISS for sending Internet traffic over amateur radio links.

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
522 an alternate low latency datapath. It alsoenables live migration of
523 a VM with direct attached VF by failing over to the paravirtual
524 datapath when the VF is unplugged.
