Subject: [PATCH] network: don't use dhcp-authoritative on static networks
"Static" DHCP networks are those where no dynamic DHCP range is
defined, only a list of host entries is used to serve permanent
IP addresses. On such networks, we don't want dnsmasq to reply
to other requests than those statically defined. But
"dhcp-authoritative" will cause dnsmasq to do just that.
Therefore we can't use "dhcp-authoritative" for static networks.
Fixes: 4ac20b3ae "network: add dnsmasq option 'dhcp-authoritative'"
