Tsirkin" , Xuan Zhuo Subject: [PATCH net-next v2 0/2] ethtool: provide the dim profile fine-tuning channel Date: Wed, 27 Mar 2024 17:19:04 +0800 Message-Id: <1711531146-91920-1-git-send-email-hengqi@linux.alibaba.com> X-Mailer: git-send-email 1.8.3.1 Precedence: bulk X-Mailing-List: netdev@vger.kernel.org List-Id: List-Subscribe: List-Unsubscribe: The NetDIM library provides excellent acceleration for many modern network cards. However, the default profiles of DIM limits its maximum capabilities for different NICs, so providing a way reusing "ethtool -C" through which the NIC can be custom configured is necessary. Please review, thank you very much!
