/**     tfrc_tx_info    -    TFRC Sender Data Structure
 *
 *      @tfrctx_x:      computed transmit rate (4.3 (4))
 *      @tfrctx_x_recv: receiver estimate of send rate (4.3)
 *      @tfrctx_x_calc: return value of throughput equation (3.1)
 *      @tfrctx_rtt:    (moving average) estimate of RTT (4.3)
 *      @tfrctx_p:      current loss event rate (5.4)
 *      @tfrctx_rto:    estimate of RTO, equals 4*RTT (4.3)
 *      @tfrctx_ipi:    inter-packet interval (4.6)
 *
 *  Note: X and X_recv are both maintained in units of 64 * bytes/second. This
 *        enables a finer resolution of sending rates and avoids problems with
 *        integer arithmetic; u32 is not sufficient as scaling consumes 6 bits.
