I didn't check the code, but I suppose that ptp4l expects to work with positive
numbers. It is possible that if forces the value to zero otherwise.

Subject: [Linuxptp-users] Port option: logMinDelayReqInterval
Hi Friends,
I have had some difficulty in using the following option.
1. I have used it as follows only at slave as keeping this option at the
master does not make sense (the slave initiates these packets). In fact, I have
varied the number between -1 to -5 to check the effect of increased frequency
of pathdelay calculations (2 DelayReq packets per second to 32 DelayReq packets
per second). Please note that I have used the negative numbers to suit the
frequency to the mean interval between packets. Is the following usage correct?
[global]
logMinDelayReqInterval -5
2. However, irrespective of the of the option number between -1 and -5, I
have always got the following message.
Ptp4l[3022.814]: port 1: minimum delay request interval 2^0
What does this mean? If the message is correct, the numbers that have been used
in the above option have not been used by the ptp4l and they have been
defaulted to 0. If that is the case, how can I use the option correctly? Should
I use the above option with any other options to cause its effect on the ptp
operation?
Please clarify.
Thanking you in anticipation,
Regards,
Chandra
