Disable IPv6 at startup?

[Grant Edwards <grant.b.edwards@xxxxxxxxx>]

What's the simplest/best way to "disable" IPv6 at runtime?

For IPv4 if you never set up any addresses or routes, then that's
"disabled enough" since it won't respond visibly to any IPv4 packets
(AFAICT).

However, for IPv6, there is a default link-local address and a
link-local route -- so even if the user application never sets up any
IPv6 configuration, the device will respond to IPv6 packets (neighbor
discovery, ping, etc).
