Help text

Tunneling means encapsulating data of one protocol type within another protocol and sending it over a channel that understands the encapsulating protocol. This particular tunneling driver implements GRE (Generic Routing Encapsulation) and at this time allows encapsulating of IPv4 or IPv6 over existing IPv6 infrastructure. This driver is useful if the other endpoint is a Cisco router: Cisco likes GRE much better than the other Linux tunneling driver ("IP tunneling" above). In addition, GRE allows multicast redistribution through the tunnel.

Saying M here will produce a module called ip6_gre. If unsure, say N.
