[PATCH net-next 10/12] net: hns3: don't allow user to change vlan filter state

From: Huazhong Tan
Date: Sat Feb 02 2019 - 09:41:23 EST


From: Jian Shen <shenjian15@xxxxxxxxxx>

When user disables vlan filter, and adds vlan device, it won't
notify the driver the update the vlan filter. In this case, when
user enables vlan filter again, the packets with new vlan tag
will be filtered by vlan filter.
