To minimize latency, jqbt employs a "Top-Down" memory allocation strategy. Memory for packet buffers is allocated directly in the DMA-able region upon the socket creation at the top of the stack, rather than re-allocating or copying buffers as the packet traverses the layers. This eliminates the memcpy operations typically seen in the hci_send_frame function.
if (dev->hw_flow_control > 0) dev->hw_send(skb); dev->hw_flow_control--; else /* Park in hardware buffer awaiting ACK */ buffer_push(dev->pending_acks, skb);

Unlike Microsoft’s generic driver, JQBT implemented a versions. Many CSR dongles from 2008–2012 reported LMP 2.x (Bluetooth 1.2) but actually supported 3.0 features. Microsoft’s driver would reject them. JQBT would spoof the LMP version to the stack, enabling EDR (Enhanced Data Rate) and sniff mode.
