Changing this flag to 'full' will clear any existing
IP address configuration for this interface and
will cause the device to use a dynamic method
(e.g. DHCP) to obtain its IP configuration and
other configuration parameter (such as gateway,
time of day, etc...) for this interface.
Setting this flag to 'inform' will allow manual IP
address configuration and yet permit other configuration
parameters (such as gateway, time of day, etc...) to
be obtained from a DHCP server.
Setting this flag to 'off' will allow manual IP
configuration but disallow any DHCP configuration.
