The completion path decrements the counter again.\n\nFor an MLO peer, the hardware reports the completion on the link that it\nused for the transmission. This link can differ from the link that the\ndriver queued the frame on. In that case, the increment and the\ndecrement go to different link wcids, and the count drifts upwards until\nit blocks the station.\n\nKeep the count on the wcid of the primary link, like the other peer-wide\nstate."
