-Subject: [PATCH] dbc2val: add duplicate filtering option
-
-To avoid generating a lot of duplicated signal events from the
-CAN messages generated by LIN polling, add a per-target
-"filter-duplicates" option that can be used for signals where
-only changes should be pushed toi the VIS server. This is
-required with the current performance of the DBC feeder to avoid
-ending up with an increasing backlog of signal commands to the
-server. This will be investigated with upstream.
