Allow IP addresses to be set in config file for
networking client/server sample applications, or
some link-layer dedicated settings like the channel.
Beware this is not meant to be used for proper
provisioning but quick sampling/testing.

If this option is set, then the networking system is automatically
initialized when the device is started. If you do not wish to do
this, then disable this and call net_config_init() in your application.

The network application needs IPv6 router to exists before continuing.
What this means that the application wants to wait until it receives
IPv6 router advertisement message before continuing.

The value is in seconds. If for example IPv4 address from DHCPv4 is not
received within this limit, then the net_config_init() call will fail
during the device startup.
