From: Yousong Zhou Date: Tue, 20 Oct 2020 02:49:18 +0000 (+0800) Subject: interface: proto_ip: order by address index first X-Git-Url: http://git.openwrt.org/?a=commitdiff_plain;h=24ce1eab4910869576406bafd0489daf0d3e6e28;p=project%2Fnetifd.git interface: proto_ip: order by address index first At the moment, dnsmasq initscript generates dhcp-range for an interface by inspecting first address of that interface from netifd ubus output. Order by address index as specified in the uci config makes netifd ubus output consistent with linux network interfaces' primary/secondary address settings. More importantly, the ubus output and dnsmasq config generation will be more predictable.
