We prefer authors as maintainer, instead of group/alias, and as you
already provide names, can this be removed?

Please sort alphabetically for 'Realtek'
Can you also add driver documentation and update release notes in this
patch?

most of the drivers has 'compat.h' or '<driver>_compat.h'
(r8169_compat.h) as compatibility layer for DPDK and define above like
structures there.
If there is no specific reason to have this file name, you can create a
compat.h for compatibility.

Do you really need all these headers here?

There is 'dev->data->dev_started' variable for exact same reason, and it
is checked in 'rte_eth_dev_stop()' level, do you need this driver
version of same flag?

This flag is set in ethdev layer level, no need to set it here.

This is already done as part of 'rte_eth_dev_pci_generic_probe()',

Dear Ferruh,
I am currently making the changes you mentioned. I would like to clarify a few questions with you.
> +F: drivers/net/r8169
> +
>
Please sort alphabetically for 'Realtek'
===> As I can see in the MAINTAINERS file, each PMD in the Networking Drivers section is not sorted alphabetically. For example, Marvell appears in several places and is not grouped together. As a result, I am unsure where to place Realtek.
Can you also add driver documentation and update release notes in this patch?
===> Do you mean that the 18th patch [PATCH v5 18/18] doc/guides/nics: add documents for r8169 pmd should be merged into the overall patch? Additionally, I don’t quite understand the “update release notes” part. Do you mean that a new release note file needs to be added in drivers/net/r8169 and updated with each patch? Or perhaps you mean that the r8169.ini and r8169.rst files should be created starting from the first patch and gradually improved as the patches are submitted?
Best Regards,
Howard Wang

This is already done as part of 'rte_eth_dev_pci_generic_probe()',
shouldn't need to do here. Can you please double check?

You are right, there are some inconsistencies,
some Marvell ones are because company acquisitions, company name changed
but order of the file not changed etc.. But there are others too.

Additionally, I don’t quite understand the “update release notes” part. Do you mean that a new release note file needs to be added in drivers/net/r8169 and updated with each patch? Or perhaps you mean that the r8169.ini and r8169.rst files should be created starting from the first patch and gradually improved as the patches are submitted?
Second one please, create documentation in this patch and improve it
gradually.
And same for the release notes (doc/guides/rel_notes/release_24_11.rst),
this patch may have the initial update announcing the new driver, if you
want to announce more updates in release notes, they can be added in
relevant patch in the series.
