[PATCH V2 net 3/3] net: hns3: fix VF ID issue for setting VF VLAN

From: Huazhong Tan
Date: Wed Dec 04 2019 - 21:12:25 EST


From: Jian Shen <shenjian15@xxxxxxxxxx>

Previously, when set VF VLAN with command "ip link set <pf name>
vf <vf id> vlan <vlan id>", the VF ID 0 is handled as PF incorrectly,
which should be the first VF. This patch fixes it.

Fixes: 21e043cd8124 ("net: hns3: fix set port based VLAN for PF")
