has_dns_options

Description:

[ Version ( since = "1.2" ) ]
public bool has_dns_options ()

NMSettingIPConfig can have a list of dns-options.

If the list is empty, there are two similar (but differentiated) states. Either the options are explicitly set to have no values, or the options are left undefined. The latter means to use a default configuration, while the former explicitly means "no-options".

Parameters:

this	the SettingIPConfig

Returns:

whether DNS options are initialized or left unset (the default).
