Please change the subject to something like "net: ethernet: nb8800:
support fixed-link DT node" and add a comment body.

The subject is pretty explicit for such a simple patch, what else
could I add that wouldn't be unnecessary chat?

It's customary to include a description body even if it's little more
than a restatement of the subject. Also, while the subject usually only
says _what_ the patch does, the body should additionally state _why_ it
is needed.

I understand, but _why_ it is needed is also obvious in this case; I
mean, without the patch "fixed-link" cannot be used.

Then say so.

Other patches may not be as obvious/simple and thus justify and
require more details.

Anyway, I added "Properly handles the case where the PHY is not connected
to the real MDIO bus" would that be ok?

Have you read Documentation/SubmittingPatches? Do so (again) and pay
special attention to section 2 "Describe your changes."

I just sent v5.

Thanks for your patience.

:-)


If for whatever reason, you or anybody else think that the comment is
not good, would you mind proposing a comment that would make everybody
happy so that the patch goes thru?
And if you or anybody else does not want the patch, could you please
say so as well?

I have to admit this process (sending patches and getting it reviewed)
could benefit from more clarifications.
For example, the process could say that at least 2 reviewers must
agree on it (on the comments made to the patch and on the patch
itself).
I could also say that reviewers are to express not only their opinion
but to clearly and unequivocally accept or reject.

For instance, right now, it is not clear to me if your comments are
"nice to have" or "blocking" the patch.
I don't know if the patch is welcome or not, etc.
So I submitted v5, but maybe it was not even necessary, it's hard to
know where in the submission process we are.

In this case, it's ultimately up to Dave Miller. He'll take into
account whatever comments others have made and decide whether he wants
to accept it.

Ok, thanks.


By the way, I know some people like the command line, email, etc. but
there ought to be other tools better suited for patch review...

Some kernel subsystems use http://patchwork.ozlabs.org/ to track status
of various patches.


Thanks, I see that netdev is part of it, and that the patches are there:

https://patchwork.ozlabs.org/patch/580217/

seems like a slight layer over plain email and mailinglists; I was thinking of something more in the line of https://www.gerritcodereview.com/
I believe Google uses Gerrit for Android.
I think Gerrit would probably be too big (and being written in Java, using Prolog and other DSLs, implementing its own Git server in Java, etc, may make some -or lots?- of kernel developers cry :-) )
However, in Gerrit it is easier to know where in the "review" process we are, because people have to explicitly give a score "+/- X" when commenting on a patch.
Also, the diff can operate between different versions of the patches themselves to see if the inlined comments were addressed.
