Subject: [PATCH v4 2/3] net/hns3: support Rx/Tx bd dump
Date: Fri, 23 Sep 2022 15:43:15 +0800	[thread overview]
Message-ID: <20220923074316.25077-3-liudongdong3@huawei.com> (raw)
In-Reply-To: <20220923074316.25077-1-liudongdong3@huawei.com>

From: "Min Hu (Connor)" <humin29@huawei.com>

This patch support query HW descriptor from hns3 device. HW descriptor
is also called BD(buffer description) which is shared memory between
software and hardware.
