From: Lijun Ou <oulijun@huawei.com> To: <luca.boccassi@gmail.com>, <stable@dpdk.org> Cc: <linuxarm@huawei.com> Subject: [dpdk-stable] [PATCH v3 19.11.6 3/6] net/hns3: report Rx drop packets enable configuration Date: Wed, 25 Nov 2020 18:58:15 +0800 Message-ID: <1606301898-51605-4-git-send-email-oulijun@huawei.com> (raw) In-Reply-To: <1606301898-51605-1-git-send-email-oulijun@huawei.com> From: "Wei Hu (Xavier)" <xavier.huwei@huawei.com> Currently, if there are not available Rx buffer descriptors in receiving direction based on hns3 network engine, incoming packets will always be dropped by hardware. This patch reports the '.rx_drop_en' information to DPDK framework in the '.dev_infos_get', '.rxq_info_get' and '.rx_queue_setup' ops implementation function.
