+
+	  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

+	  This is essentially a bit-bucket device (i.e. traffic you send to

+	  address. It is most commonly used in order to make your currently
+	  inactive SLIP address seem like a real address for local programs.
+	  If you use SLIP or PPP, you might want to say Y here. It won't

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

+
+	  If you intend to use Fibre Channel, you need to have a Fibre channel
