Subject: [PATCH net 1/2] selftests/ptp: Add -x option for testing PTP_SYS_OFFSET_EXTENDED

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.

I see I've accidentally sent an older revision of the patch series, before I've rebased properly and before I used checkpatch.
I will send the fixed one (and to the correct tree this time) in a v2 series.
Replying to the first patch because the cover letter did not land in my inbox, somehow.
I hope this is the right thing to add:

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.

Eh, didn't work, the bot does a simple == comparison:

https://github.com/kuba-moo/nipa/blob/master/mailbot.py#L294

so "Maftei, Alex" <[email protected]>
vs Alex Maftei <[email protected]>

won't match.
