[PATCH net-next 0/3] net: ptp: use common defines for PTP message types in further drivers

[PATCH net-next 0/3] net: ptp: use common defines for PTP message types in further drivers

[Christian Eggers]

This series replaces further driver internal enumeration / uses of magic
numbers with the newly introduced PTP_MSGTYPE_* defines.

I think that I have found an addtional one in the Microsemi VSC85xx PHY driver.

Sorry for this, I sent my 2nd series too early. These errors will disappear as
soon as the first series has been merged.

But:

1. Checkpatch complains about:
WARNING: From:/Signed-off-by: email address mismatch: 'From: Christian Eggers <ceggers@arri.de>' != 'Signed-off-by: Christian Eggers <ceggers@gmx.de>'

2. This series does not build, which fails the CI [1][2] and also
required me to fetch the dependencies that are currently under review
[3]. I believe it is generally discouraged to create dependencies
between patch sets that are under review for exactly these reasons. I
don't know what are Jakub's preferences, but had this happened on our
internal patchwork instance, I would just ask the author to submit
another version with all the patches.

Anyway, I added all six patches to our regression as we have some PTP
tests. Will let you know tomorrow.

unfortunately I changed this after running checkpatch. My intention was to 
separate my (private) weekend work from the patches I do while I'm on the job.

this was also not by intention. Vladimir found some files I missed in the
first series. As the whole first series had already been reviewed at that time,
I wasn't sure whether I am allowed to add further patches to it. Additionally
I didn't concern that although my local build is successful, I should wait
until the first series is applied...

No problem. Just make sure that authorship and Signed-off-by agree. You
can use:

Jakub has the final say, so I assume he will comment on that.

Regardless, thanks for the patches.

The pre-requisite was just merged, so please collect all the review tags
you got so far and repost.

When I said that, what I was thinking of (although it might have not
been clear) was that if you send further patches, you send them _after_
the initial series is merged.

Alternatively, it would have been just as valid to resend the entire
series, as a 3+3 patchset with a new revision (v3 -> v4), with review
tags collected from the first three, and the last 3 being completely
new. Jakub could have superseded v3 and applied v4.

The idea behind splicing N patches into a series is that they are
logically connected to one another. For example, a patch doesn't build
without another. You _could_ split logically-connected patches into
separate series and post them independently for review, as long as they
are build-time independent. If they aren't, well, what happens is
exactly what happened: various test robots will report build failures,
which from a maintainer's point of view inspires less confidence to
apply a patch as-is. I would not be surprised if Jakub asked you to
resend with no change at all, just to ensure that the patch series
passes build tests before merging it.
