Did you really have to quote 400kb of original patch to
make that prefixing statement to David?

I would prefer my name not be listed as a Signed-off-by.

I don't have a card, I never tested it, etc.  What I did
do is a light review and made a couple of trivial patch
suggestions about how you might make logging code a bit
smaller.

Thanks and cheers, Joe

There is no worse act than quoting a huge patch, only to provide two
lines of text.

Doing so is an enormous waste of resources, bandwith, and people's
time.  Everyone single person on the CC: list and the various mailing
lists had to consume this entire patch a second time, just to see
these two small lines of text you wanted to add.

Are you even aware of the ramifications of your actions at all?

If this lack of consideration extends to your actual coding as well, I
very much dread reviewing your work.

Please be incredibly more considerate and thoughtful with your email
etiquette, or I will just plain flat out ignore your patch submissions
entirely.

You should never EVER add a signoff, or any other kind of tag, of
another person unless they give it to you explicitly.  It is beyond
rude to do this without that person's permission.

You qualcomm guys are really mishandling this patch submission,
and just like last time you are steadily pissing me off.

You have a very low level of consideration for other people who feel
the burdon of your work, and you often have no idea what the hell you
are doing.

Stop this TOP POSTING, it's bad etiquette on a technical mailing list.

Look at how other people write their email responses on this mailing
list.  They first provide a quoted portion of what they are replying
to:

> Quoted
> something like this.

And then they provide their response UNDERNEATH.

When you provide your response at the top of the email, it is unexpected,
and makes more work for people reading what you write.

You guys are doing everything possibly wrong.

You have unnecessarily quoted a HUGE patch just to provide some ancillary
in formation.

You are TOP POSTING.

You added a signoff of someone who did not give you explicit permission
to do so.

And you seem to not comprehend nor care about the implications or effects
of your actions that are hurting other people and creating a huge brudon.

I very much intend to simply ignore your work completely until you can
get your act in gear, write proper emails, and submit patches
properly.

It is the only deterrant I have for your incredibly rude and
inconsiderate behavior.

Hi David,

Please calm down. I will follow rule of sending email from now on. Sorry for causing
your trouble. Luis has ever asked joe for adding as a Signed-off-by. At that time joe agreed
with it. If joe prefers his name not be listed as a Signed-off-by, I will respect his decision.
alx driver is innocent. Please help review.  Thanks

At this time I don't think what I did amounts to a
sign-off of the whole driver.

I appreciate the thoughtfulness of trying to credit
me as a person by improving the driver a little.  I
just wouldn't say I signed off on the whole thing.

cheers, Joe

This driver support two new ethernet chipsets:
1969:1091 - AR8161 Gigabit Ethernet
1969:1090 - AR8162 Fast Ethernet

Qualcomm Atheros(QCA) is commiting to fix all bugs found on this driver.
This driver is also permissively licensed thereby enabling developers of
other OSes to cherry pick this driver to port to their OS.

Test including build/install/uninstall/dhcp/ping/iperf/wol/reboot/etc.
is passed on the supported chipsets.

This driver and patch also have addressed all sparse and checkpatch
warnings.

I'm curious, did Luis ask on list or off? When I ask someone for a
Signed-off-by tag, I always ask them to post it to the list, even when
they have given it to me privately. I like others to see that someone
explicitly gave me their permission, as I would never add a Signed-off
tag for someone else.

The Signed-off tag has some legal bindings (all other tags are for
credit/info only). It is that person saying that the changes they made
to a patch are theirs and are giving the right to distribute it. It is
also used by those that take the changes and insert it into the
repository.

From Documentation/SubmittingPatches:

  The sign-off is a simple line at the end of the explanation for the
  patch, which certifies that you wrote it or otherwise have the right to
  pass it on as an open-source patch.

Joe, If you actually modified part of the code in the patch, you do have
the right to add a signed-off-by tag. If you just made suggestions or
reviewed, then a 'Suggested-by' or 'Reviewed-by' tag would be more
appropriate.

  The Signed-off-by: tag indicates that the signer was involved in the
  development of the patch, or that he/she was in the patch's delivery
  path.

Off vger lists with some qca list or exploder added.

I believe I posted all patches I signed-off to vger lists.

Yes, I sent signed-off patches to their original RFC submission
(back last year?).  To me, this single large patch is like a
snapshot of a git tree and not all contributors to that git
tree should be noted as signers of the entire thing.

Ouch, that looks like we are losing all history.

One large patch should not be submitted. If it was developed in steps,
then it is best to show those steps when they are incorporated into the
Linux repository.

Sure, the patches may be reworked and folded together where appropriate,
but when I read "this single large patch is like a snapshot of a git
tree", that right there is a red flag.

I don't think this has ever been a requirement for new drivers.

The alterations to the description of atl1c ought to be broken out as a
separate patch, though.

And that is why your SOB was kept.

I am not sure we really ever addressed this technical difference and
from what I have seen we always run into this question on new driver
submissions.

Entity x goes on and posts driver joojoo-1, and we some folks in the
community may merge such patch onto their tree and edit the driver and
send some of their own changes and improvements to the developers /
mailing list. Typically if the patches sent had a SOB tag the right
thing to due given the legal implications of the Developer's
Certificate of Origin is to add those SOBs to the new driver
submission if company x goes on and posts joojoo-2.. but...

> Ouch, that looks like we are losing all history.

Agreed! It'd be best instead to have such changes as part of a linear
history somewhere so maybe what would be right prior to inclusion
upstream is for such patches to be merged on an external github tree
or wherever to be able to keep record of the submissions done during
development. Then upon submission to the Linux kernel again as
joojoo-2 instead of joojoo-1 company x would simply provide their own
SOB, and the record of the previous SOBs would be kept on the forked
git tree.

Whether or not it is required to have the SOB tog of previous patch
submitters is not clear but to me its not necessary if you have a
record somewhere that they were submitted and merged in some other
tree. The mailing list alone may serve as a good place holder for this
information as well so a separate tree may not be required.

So -- are we OK to *not* include SOBs of evolutions sent to developers
of joojoo-1 when company x submits joojoo-2 so long as those patches
were sent publicly or a record is kept somewhere ?

> One large patch should not be submitted. If it was developed in steps,

Sure, but at times some changes are asked after a submission of
joojoo-1, and at times this may be ongoing until maybe even joojoo-10,
before we are happy to merge it upstream.

And lets be fair, some folks *may* want their SOB passed along to the
second joojoo-2, its hard to please everyone but so long as we can
decide on a method -- then great, we don't have to come back to this
again and then we can add this as documentation. I'm inclined to
prefer to not have the small patch submitters SOB tag if their patch
to joojoo-1 was public and in it they did have a SOB tag, given that
in practice *a few* secondary patch submitters tend to get surprised
when their SOB is added to a secondary patch submission if they only
contributed a few lines. To be clear the SOB does not have anything to
do with how many lines you contributed, its meaning is here:

http://gerrit.googlecode.com/svn-history/r1526/documentation/2.1.2/user-signedoffby.html

So even if those secondary patch submitters *think* it has to do with
volume of code, perhaps its best in practice to not include them so
long as we have a record of the original small patch submission
publicly and with a SOB tag.

The strcpy is useful. netdev->name is set as pci_name in front. So the strcpy restores it.

Are you doing this just to influence the initial driver log messages?

Don't do that, it's gross.
