Subject: dnsmasq: Add match section support
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=32f4777530bc814cb878c0436bc26cded53a3a8b;p=openwrt%2Fstaging%2Fjogo.git

dnsmasq: Add match section support

Match sections allow to set a tag specified by the option networkid if the client
sends an option and optionally the option value specified by the match option.
The force option will convert the dhcp-option to force-dhcp-option if set to 1 in
the dnsmasq config if options are specified in the dhcp_option option.

config match
    option networkid tag
    option match 12,myhost
    option force 1
    list dhcp_option '3,192.168.1.1'
