Subject: [PATCH net-next 04/12] net: hns3: fix set port based VLAN issue for VF
From: Jian Shen <shenjian15@...wei.com>
In original codes, ndo_set_vf_vlan() in hns3 driver was implemented
wrong. It adds or removes VLAN into VLAN filter for VF, but VF is
unaware of it.
This patch fixes it. When VF loads up, it firstly query the port
base VLAN state from PF. When user change port based VLAN state
from PF, PF firstly check whether the VF is alive. If the VF is
alive, then PF notifies the VF the modification; otherwise PF
configure the port based VLAN state directly.
Fixes: 46a3df9f9718 ("net: hns3: Add HNS3 Acceleration Engine & Compatibility Layer Support")
