Applying tcpip_adapter_dhcps_option(TCPIP_ADAPTER_OP_SET,
TCPIP_ADAPTER_DOMAIN_NAME_SERVER, …) with option value 0 now disables
the DNS offer. It previously would only switch the DNS offer to sending
the interface IP address instead of the DNS set. If enabled now with an
unset DNS IP (0.0.0.0) it will fallback to the interface IP.
