This read-write object selects the drop policy, other, alwaysDrop, tailDrop, or randomDrop, that governs how this action handles packets when its associated queue is congested. An admin chooses randomDrop together with configured min/max thresholds to implement early congestion avoidance, or tailDrop for simpler hard-limit dropping, or alwaysDrop for an action meant to discard all matching traffic outright. For example, an admin wanting smoother congestion behavior for a bursty traffic class would select randomDrop rather than tailDrop, so drops begin gradually as the average queue depth rises instead of all at once when the queue fills.
