Subject: [RFC v1 14/22] eth: bnxt: always set the queue mgmt ops
Date: Mon, 28 Jul 2025 12:04:18 +0100	[thread overview]
Message-ID: <8eb9793e5bd1100dd6db95e0c84cac32f8b44152.1753694914.git.asml.silence@gmail.com> (raw)
In-Reply-To: <cover.1753694913.git.asml.silence@gmail.com>

From: Jakub Kicinski <kuba@kernel.org>

Core provides a centralized callback for validating per-queue settings
but the callback is part of the queue management ops. Having the ops
conditionally set complicates the parts of the driver which could
otherwise lean on the core to feel it the correct settings.

Always set the queue ops, but provide no restart-related callbacks if
queue ops are not supported by the device. This should maintain current
behavior, the check in netdev_rx_queue_restart() looks both at op struct
and individual ops.
