I wasn't sure if changing the names of the patch and the intent is what 
would constitute a new "patch series" so then restart the counter for 
the counters or not. I had figured "two new patches, two new counters"
which I understand now was incorrect.

In this particular case, should I have stuck with my first submission
title:
[PATCH v2 net] bug fix when writing MAC speed
and submitted the two patches? 

I assume it would only cause headaches if I incremented the counter and
changed the name to something like
[PATCH v2 net] remove unnecessary register writes
or something simliar? Although your example below suggests I should
maybe submit the next set as
[PATCH v3 net] ocelot phylink fixes

I've been using --to-cmd and --cc-cmd with get_maintainer.pl. If this is
ill-advised, I'll stop. I noticed it seemed to determine the list on a
per-patch-file basis instead of generating one single list.

Thank you for all this. I understand you have better things to do than
to hold my hand through this process, so I greatly appreciate your help.
