What is lpBridgePortReceiveUnknownDiscards?

The number of frames discarded because the destination address was unknown to the bridge; this counter is only meaningful for FDDI ports, and only when the bridge is an EEM or an ESM operating in express mode. A climbing value points to destination lookups missing in the learning table, worth checking against expected traffic patterns.
