+ 4.1.6 RAW socket option CAN_RAW_JOIN_FILTERS
+
+ The CAN_RAW socket can set multiple CAN identifier specific filters that
+ lead to multiple filters in the af_can.c filter processing. These filters
+ are indenpendent from each other which leads to logical OR'ed filters when
+ applied (see 4.1.1).
+
+ This socket option joines the given CAN filters in the way that only CAN
+ frames are passed to user space that matched *all* given CAN filters. The
+ semantic for the applied filters is therefore changed to a logical AND.
+
+ This is useful especially when the filterset is a combination of filters
+ where the CAN_INV_FILTER flag is set in order to notch single CAN IDs or
+ CAN ID ranges from the incoming traffic.
