The r8152.c is too large to find out the desired part, so I speparate it
into r8152_main.c and r8152_fw.c.

r8152: group the usb ethernet of realtek
r8152: separate the r8152.c into r8152_main.c and r8152_fw.c

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, greg k-h ^ permalink raw reply [flat|nested] 12+ messages in thread

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 ^ permalink raw reply [flat|nested] 12+ messages in thread

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. thanks, greg k-h ^ permalink raw reply [flat|nested] 12+ messages in thread

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.

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? thanks, greg k-h ^ permalink raw reply [flat|nested] 12+ messages in thread

I got it. I will submit them with the support of new device in the future. Best Regards, Hayes ^ permalink raw reply [flat|nested] 12+ messages in thread
