Subject: [PATCH V2 net-next 3/6] net: hns3: optimize the code when update the tc info
Date: Fri, 5 Feb 2021 16:32:46 +0800	[thread overview]
Message-ID: <1612513969-9278-4-git-send-email-tanhuazhong@huawei.com> (raw)
In-Reply-To: <1612513969-9278-1-git-send-email-tanhuazhong@huawei.com>

From: GuoJia Liao <liaoguojia@huawei.com>

When update the TC info for NIC, there are some differences
between PF and VF. Currently, four "vport->vport_id" are
used to distinguish PF or VF. So merge them into one to
improve readability and maintainability of code.
