TAP interface vlan-qos throw "opeartion not supported" by kernel 3.10.


Hi,
I have created the tap interface and vlan on top of it and its working as expected. when i try to set the vlan-qos (Vlan priority bit) it throws the operation not supported error. I'm using RHEL7 and kernel version 3.10

7: wan1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN mode DEFAULT qlen 500
link/ether 66:8d:bc:4c:20:48 brd ff:ff:ff:ff:ff:ff
11: wan1.201@wan1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state LOWERLAYERDOWN mode DEFAULT
link/ether 66:8d:bc:4c:20:48 brd ff:ff:ff:ff:ff:ff


[root@sys-214-33 build]# ip link set dev wan1.201 vf 11 vlan 201 qos 3
RTNETLINK answers: Operation not supported

[root@sys-214-33 build]# ip link set dev wan1 vf 7 vlan 201 qos 7
RTNETLINK answers: Operation not supported

What is the issue here?
Is there any other alternate mechanism to set the vlan-qos for the interface.

Thanks
Palani
