    Description

      Allow the llstat utility to work properly on clients, so that specifying "llite" or "mdc" as an argument will print out useful stats.

      It would also be useful to allow aggregating stats across multiple OSC devices.

            It is now possible to specify stats files using the same syntax as "lctl get_param", for example "llstat osc.*OST0000*.stats" or equivalent.

            What it doesn't yet do is aggregate stats between multiple stats files that match a "*" like "llstat osc.*.stats" into a single output. It currently picks the first matching file and reports only those stats.
