Functions
static void	send_queued_packet (struct collect_conn *c)
	This function is called when a queued packet should be sent out. More...
static void	retransmit_callback (void *ptr)
	This function is called from a ctimer that is setup when a packet is sent. More...
static void	retransmit_not_sent_callback (void *ptr)
	This function is called from a ctimer that is setup when a packet is first transmitted. More...
static uint16_t	rtmetric_compute (struct collect_conn *tc)
	This function computes the current rtmetric by adding the last known rtmetric from our parent with the link estimate to the parent.
static void	bump_advertisement (struct collect_conn *c)
	This function is called when the route advertisements need to be transmitted more rapidly.
static void	update_parent (struct collect_conn *tc)
	This function is called to update the current parent node. More...
static void	update_rtmetric (struct collect_conn *tc)
	This function is called whenever there is a chance that the routing metric has changed. More...
static void	retransmit_current_packet (struct collect_conn *c)
	This function is called to retransmit the first packet on the send queue.
