This read-only Counter32 tallies, per its source description, the number of data packets sent by this station that the host has positively acknowledged, incrementing by n when the host batches an acknowledgment for a group of n packets. Admins use this to confirm successful, host-acknowledged data delivery for this station, comparing it against esconStationDataPacketsSent to compute an effective acknowledgment rate. For example, a growing gap between DataPacketsSent and PositiveAckDataPackets over time would suggest acknowledgments are lagging or being lost, worth investigating alongside the retransmission counter.
