Subject: dnsmasq: allow forcing options
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=0e540ec90d9a689ed6417334bb9ec4882da06cfd;p=openwrt%2Fstaging%2Fstintel.git

dnsmasq: allow forcing options

The option 'force' when set to '1' will transform a dhcp-option to dhcp-option-force instead in the config.

This is useful for forcing options to be sent back to a client (even options it didn't ask for).
