Subject: [dpdk-dev] [PATCH 6/6] net/hns3: fix duplicate VLAN
Date: Fri, 22 Nov 2019 20:06:24 +0800
Message-ID: <20191122120624.4963-7-xavier.huwei@tom.com> (raw)
In-Reply-To: <20191122120624.4963-1-xavier.huwei@tom.com>

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

When setting duplicate vlan, hns3 driver will also add vlan entry
to vlan linked list, and this is unreasonable.

This patch adds checking whether the VLAN to be added already exists
in the linked list and preventing adding duplicate vlan.

Fixes: 411d23b9eafb ("net/hns3: support VLAN")
Cc: stable@dpdk.org
