No problem with the commit splits and orders, thanks for the update there.

Only comment in this patch is 'RTL_DEV_PRIVATE' macro is not used in the
patch and it can be added when you use the macro, so this is a simple issue.

Also I have a comment that build fails after some patchs, this also does
not require changing how patch split done, just fix build after each patch.

I am not sure if there is a misunderstanding but change requests are
mostly simple ones, I expect they can be fixed in one or two days, and I
am hopping to merge the driver in -rc2 or -rc3 at worst.

Ahh, I see, matching is simple for 8125, device id and product number is
same :), is it same for all supported devices?
	{ RTE_PCI_DEVICE(PCI_VENDOR_ID_REALTEK, 0x8125) },
	{ RTE_PCI_DEVICE(PCI_VENDOR_ID_REALTEK, 0x8162) },
	{ RTE_PCI_DEVICE(PCI_VENDOR_ID_REALTEK, 0x8126) },
	{ RTE_PCI_DEVICE(PCI_VENDOR_ID_REALTEK, 0x5000) },
