5.47 Receive Queue Teardown Register (RX_QUEUE_TEAR_DOWN)

Each of this register'sbits corresponds to one of the 16 RX buffer descriptor queues. If a 1 is written to a bit, the teardown process is started for the associated queue. RX_QUEUE_TEAR_DOWN is shown in Figure 110 and described in Table 115. For additional programming information, see Section 2.3.4.1 .
