Subject: Re: [dpdk-dev] [PATCH v2] ethdev: change queue release callback
Date: Thu, 16 Sep 2021 10:09:41 +0200	[thread overview]
Message-ID: <16158406.yydg6pnXu9@thomas> (raw)
In-Reply-To: <20210915130202.146589-1-xuemingl@nvidia.com>

> To align with other eth device queue configuration callbacks, cleanup
> queue release callback API by changing RX and TX queue release callback
> API parameter from queue object to device and queue index.

Please split the explanation in multiple sentences,
so it allows taking a breath while reading :)
A good method is to start with explaining the status:
	most callbacks use queue ID
	queue release callbacks use queue object
Then explain what is done:
	queue release callbacks are changed to use queue ID
	all drivers are adapted
	empty callbacks are removed in some drivers

> This patch allows NULL callback to avoid defining empty callbacks.

This note does not fully explain why using the queue ID helps.

Why removing this check?
It is changing the behaviour.
