From: Jo-Philipp Wich Date: Wed, 21 Jun 2017 14:48:41 +0000 (+0200) Subject: dnsmasq: introduce config support for forced DHCP options X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=d0f6a514b10aece3db265d8ef1d5e3b2bce7d121;p=openwrt%2Fstaging%2Fluka.git dnsmasq: introduce config support for forced DHCP options Introduce a new UCI list setting `list dhcp_option_force` which is available in sections of type `dnsmasq` and `dhcp`. The `dhcp_option_force` setting has the same semantics as `dhcp_option` but generates `dhcp-option-force` directives instead of `dhcp-option` ones in emitted native configuration.
