Subject: [PATCH V2 net-next 1/7] net: hns3: fix error VF index when setting VLAN offload
Date: Thu, 5 Sep 2019 21:31:36 +0800 [thread overview]
Message-ID: <1567690302-16648-2-git-send-email-tanhuazhong@huawei.com> (raw)
In-Reply-To: <1567690302-16648-1-git-send-email-tanhuazhong@huawei.com>
From: Jian Shen <shenjian15@huawei.com>
In original codes, the VF index used incorrectly in function
hclge_set_vlan_rx_offload_cfg() and hclge_set_vlan_rx_offload_cfg().
When VF id is greater than 8, for example 9, it will set the
same bit with VF id 1.
This patch fixes it by using vport->vport_id % HCLGE_VF_NUM_PER_CMD /
HCLGE_VF_NUM_PER_BYTE as the array index, instead of vport->vport_id /
HCLGE_VF_NUM_PER_CMD.
Fixes: 052ece6dc19c ("net: hns3: add ethtool related offload command")
