This object turns packet counting filtered by a specific destination MAC address on or off. This is the destination-side mirror of the source-count flag, letting an admin instead investigate how much traffic is being sent toward one specific suspected node, useful when the concern is a node being overwhelmed as a target rather than one flooding as a source. Enabling this while targeting a specific node's address lets an admin check whether that node is on the receiving end of an unusually large amount of ring traffic, which might explain that node reporting congestion or queue issues.
