The -x option (where 'x' stands for eXtended) takes an argument which
represents the number of samples to request from the PTP device.
The help message will display the maximum number of samples allowed.
Providing an invalid argument will also display the maximum number of
samples allowed.

Hi Alex,

As I can see you will need to send another patch, I have just a small
comment bellow.

The 'X' needs to be part of the next patch, as you introduce here only 'x'.

Hi Horatiu,

v2 of the series will have that fixed.
I've accidentally sent an older revision of this patch series, before I've rebased the changes properly.
