From what I see, a management frame is sent from an AC queue and when we get the Tx response for this frame, we get sta_id = AP, tid = 0 (and the bug is probably here). So we modify the counters for sta_id = AP, and tid = 0, and this messes up everything. I guess I need to see why I don't see this issue, and see how to give a hint to the Tx response path that counters shouldn't be modified. --------------------------------------------------------------------- Intel Israel (74) Limited This e-mail and any attachments may contain confidential material for the sole use of the intended recipient(s).
