Flow control is implemented by inspecting the qdisc queue length in order to detect potential overflow on the TX queue. When a threshold is reached flow-off is sent upwards in the CAIF stack. At the same time the skb->destructor is hi-jacked by orphaning the SKB and the original destructor is replaced with a "flow-on" callback. When the "hi-jacked" SKB is consumed the queue should be empty, and the "flow-on" callback is called and xon is sent upwards in the CAIF stack.
