Subject: [dpdk-dev] [PATCH 4/4] net/hns3: refactor multi-process initialization
Date: Tue, 2 Nov 2021 09:38:29 +0800	[thread overview]
Message-ID: <20211102013829.42345-5-humin29@huawei.com> (raw)
In-Reply-To: <20211102013829.42345-1-humin29@huawei.com>

From: Huisong Li <lihuisong@huawei.com>

Currently, the logic of the PF and VF initialization codes for multiple
process is the same. A common function can be extracted to initialize and
unload multiple process.
