hello team,
I found that port_nrate_calculate() save the first ingress1 before slave
clock jumping, if the offset of master and slave is too large, this may
results in an extremly small nrate_ratio value, and cause the nagative
delay issue.
so, is this a problem please?
what about port_nrate_calculate() sampling the first ingress1 until servo
entering lock state?
like this:
1028 if (tmv_is_zero(n->ingress1) && *clock_servo_state(p->clock) ==
SERVO_LOCKED*) {
1029 n->ingress1 = ingress;
1030 n->origin1 = origin;
1031 return;
1032 }
734 ptp4l[61.809]: negative delay -2267723
735 ptp4l[61.809]: delay = (t2 - t3) * rr + (t4 - t1)
736 ptp4l[61.809]: t2 - t3 = +0
737 ptp4l[61.809]: t4 - t1 = -4535446
* 738 ptp4l[61.809]: rr = 0.000000003*
*Thanks*
