int tfrc_rx_handle_loss	(	struct tfrc_rx_hist *	h,
		struct tfrc_loss_hist *	lh,
		struct sk_buff *	skb,
		const u64	ndp,
		u32()(struct sock )	calc_first_li,
		struct sock *	sk
	)

tfrc_rx_handle_loss - Loss detection and further processing : The non-empty RX history object : Loss Intervals database to update : Currently received packet : The NDP count belonging to : Caller-dependent computation of first loss interval in : Used by (see tfrc_lh_interval_add)

Chooses action according to pending loss, updates LI database when a new loss was detected, and does required post-processing. Returns 1 when caller should send feedback, 0 otherwise. Since it also takes care of reordering during loss detection and updates the records accordingly, the caller should not perform any more RX history operations when loss_count is greater than 0 after calling this function.

tfrc_rx_hist_sample_rtt - Sample RTT from timestamp / CCVal Based on ideas presented in RFC 4342, 8.1. Returns 0 if it was not able to compute a sample with given data - calling function should check this.
