``conf/default/*``:
Change the interface-specific default settings.
These settings would be used during creating new interfaces.
``conf/all/*``:
Change all the interface-specific settings.
[XXX: Other special features than forwarding?]
conf/all/disable_ipv6 - BOOLEAN
Changing this value is same as changing ``conf/default/disable_ipv6``
setting and also all per-interface ``disable_ipv6`` settings to the same
value.
Reading this value does not have any particular meaning. It does not say
whether IPv6 support is enabled or disabled. Returned value can be 1
also in the case when some interface has ``disable_ipv6`` set to 0 and
has configured IPv6 addresses.
conf/all/forwarding - BOOLEAN
Enable global IPv6 forwarding between all interfaces.
