 setting option ignore to 1 in the lan interface section of the dhcp config
 uses the -I option which causes dnsmasq to ignore that interface.

 If one wants DNS resolution/caching from dnsmasq disabling DHCP should use
 option -2 to disable DHCP but not DNS.

 This can be as simple as changing -I to -2 on line 188 of
 /etc/init.d/dnsmasq  however this would leave DNS enabled on the WAN
 interface.

 Tested on r10958
