FS#1177 - dnsmasq spams syslog on loss of WAN connection
User who did this - Alexei C (Adminiuga)
----------
I can see the same messages from DNSmasq in the snapshot from 12/21/17
Firmware Version OpenWrt SNAPSHOT r5597-dda2229 / LuCI Master (git-17.351.54937-a2a1c35)
Only in my case the WAN interface was disabled deliberately, as I'm using it as an AP only.
