Rename r8152.c with r8152_main.c. Move some basic definitions from
r8152_main.c to r8152_basic.h. Move the relative code of firmware
from r8152_main.c to r8152_fw.c. Rename the definition of "EFUSE"
with "USB_EFUSE".

That is a lot of different things all happening in one commit, why?

Please break this up into "one patch per change" and submit it that way.

But the real question is why break this file up in the first place?
What is wrong with the way it is today?  What future changes require
this file to be in smaller pieces?  If none, why make this?  If there
are future changes, then please submit this change when you submit
those, as that would show a real need.

thanks,

I plan to separate the file into two files. And
I find I need an additional header file for it, so
The patch includes adding that header file.

The purpose is let me easy to maintain the driver.
The code is larger and larger. And I find that the
r8169.c has been separated into three files.
Therefore, I think maybe I could split the driver
into small parts like r8169. Then, the code wouldn't
be complex.

Should I abandon these patches?

Best Regards,
Hayes

You also do other things, like renaming defines, which is not just
moving code around, right?

I do not know, is it really easier to find things in 3 different files
instead of one?  That's up to you, but you did not say why this change
is needed.

Yes. You are right.

We support a new chip or feature with a test driver.
The test driver is similar with the upstream driver, except
the method of the firmware. After we confirm that the
test driver work fine, we compare the differences with
the upstream driver and submit patches. And the code
about firmware takes us more time to find out the
differences. Therefore, I wish to move the part of
the firmware out.

I don't sure if it is acceptable for such patches.
If it is unacceptable, I would abandon these patches.

Best Regards,
Hayes

So resend the series and only do "one thing per patch" please.

Great, then submit the broken up driver as part of a patchset that adds
new device support, as that makes more sense when that happens, right?

I got it. I will submit them with the support of new device in the future.
