You still need to add following lines to the loadConfig() method, otherwise
those properties won't be filled when editing an existing connection:
m_tmpIpv4Setting.setDhcpHostname(ipv4Setting->dhcpHostname());
m_tmpIpv4Setting.setDhcpSendHostname(ipv4Setting->dhcpSendHostname());
m_tmpIpv4Setting.setDadTimeout(ipv4Setting->dadTimeout());
