Bits 7 to 0: Receive Queue Low Threshold (RQLT7 to RQLT0). The receive queue low threshold for the connection, in increments of 32 packets of 2048 bytes each. The value of this register is multiplied by 32 * 2048 bytes to determine the byte location of the threshold. Note that the receive queue is for data that was received from the Ethernet Interface to be sent to the Serial Interface.
