dnsmasq: add support for set: and tag: pairs
On my network, I have a variety of machines and appliances, some of which need different configuration issues than the default options. For example: config host option name 'client' option mac '00:01:02:03:04:05' option ip '192.168.1.20' option tag 'acme' config tag acme option force '1' list dhcp_option 'option:router,192.168.1.253' list dhcp_option 'option:domain-name,acme.com' list dhcp_option 'option:domain-search,acme.com,redfish-solutions.com' which allows me to override the default router for my client's host, as well as its domain-name, and its domain-search. this causes the following config lines: dhcp-host=00:01:02:03:04:05,set:acme,192.168.1.20,client dhcp-option-force=tag:acme,option:router,192.168.1.253 dhcp-option-force=tag:acme,option:domain-name,acme.com dhcp-option-force=tag:acme,option:domain-search:acme.com,redfish-solutions.com This could be useful elsewhere, for instance, if you have an IP CCTV that you don't want to have a default-route, etc. Signed-off-by: Philip Prindeville <philipp@redfish-solutions.com> SVN-Revision: 31815
