As it is right now net.ipv6.conf.all.* are mostly ignored and instead
we're only making decisions based on interface specific settings. These
settings are coppied from net.ipv6.conf.default and changing either all
or default settings have no effect.

Although this is the right idea conceptually, it risks creating unhappy
users because it changes the semantics of the API. This will probably break
somebody's configuration.

You're right but in this case I feel we are moving in the right
direction. While the
behavior will change in some cases this change is only adding well known ipv4
behavior for ipv6 sysctls. In fact documentation briefly mentioned that
net.ipv6.conf.all.* should change all the interface-specific settings
but that was
not the case until now.
