In most time, it works fine. But there is a time window before the service task shceduled and net device being registered. So if user adds VLAN at this time, the driver will not update the VLAN filter state, and the port VLAN filter remains enabled. To fix the problem, if support modify VLAN filter state but not support bypass port VLAN filter, set the port vlan filter to "off".
