Supported token pop modes are as follows, and they impact core scheduling affinity for ldb ports. AUTO_POP: Pop the CQ tokens immediately after dequeueing. DELAYED_POP: Pop CQ tokens after (dequeue_depth - 1) events are released. Supported on load-balanced ports only. DEFERRED_POP: Pop the CQ tokens during next dequeue operation.
