We should use wrapper functions vlan_vid_[add/del] instead of
ndo_vlan_rx_[add/kill]_vid. Otherwise, we might be not able to communicate
using vlan interface in a certain situation.
Example of problematic case:
vconfig add eth0 10
brctl addif br0 eth0
bridge vlan add dev eth0 vid 10
bridge vlan del dev eth0 vid 10
brctl delif br0 eth0
In this case, we cannot communicate via eth0.10 because vlan 10 is
filtered by NIC that has the vlan filtering feature.
