答复: [PATCH v6 01/17] net/r8169: add PMD driver skeleton

[王颢 <howard_wang@realsil.com.cn>]

Dear Ferruh,

I apologize for the issues that have arisen during the process of splitting a complete driver into several small patches.

===> I referred to Atlantic’s approach for this, and as a matter of fact, his first commit message was done in this manner. 
I will think again about how it should be modified.

net/atlantic: add PMD driver skeleton
Makefile/meson build infrastructure, atl_ethdev minimal skeleton,
header with aquantia aQtion NIC device and vendor IDs.

What do you think to add macros for the PCI device IDs, naming them makes it easier to know which devices are supported.

===> Regarding the device ID, for 0x8125, the supported device is indeed called 8125. So, should we name a macro like DEVICE_ID_RTL8125 to replace it?

Best regards,
Howard Wang

This macro is only used a few patches later, what do you think to add this macro when used?
