Dear
   uci:foreach("network", "interface",
        function (section)
            local ifc = section[".name"]
            if ifc ~= "loopback" then
                entry({"admin", "network", "network", ifc},
                 true,
                 ifc:upper())
            end
        end
    )
      Sorry  , I can't still understand the setence " local ifc = section[".name"]", why can it get the section name by using section[".name"]"?
