Thanks for your help! Unfortunately, setting those values doesn't work
for me. I get the following errors:
sudo ptp4l -2 -i enp1s0f1 -f ./default-new-master.cfg -m
-1.0 is an out of range value for option pi_proportional_const at line 73
failed to parse configuration file ./default-new-master.cfg
or
$ sudo ptp4l -2 -i enp1s0f1 -f ./default-new-master.cfg -m
P is a malformed value for option pi_proportional_scale at line 75
failed to parse configuration file ./default-new-master.cfg
I am on tag v4.1. Any ideas why this is not working?

I have a 82599ES from Intel [1]. I found the paramters you were referring to
but I am not sure how to adjust them. Can you give me some guidance for this
if you get a chance?
Try this:
pi_proportional_exponent -1
pi_integral_exponent -1
pi_proportional_scale P
pi_integral_scale I
where P and I are from one line of this table:
0.316 0.01562
0.158 0.00391
0.079 0.00098
0.040 0.00024
0.020 0.00006
This is the NTPv4 (RFC 5905) PLL at five different gains. If the sync
interval is -4 (16 sync messages per second), try the middle pair
first.
