I agree with you.
But I want to do such as:
|double tag packet|------>|OpenFlowSwitch|------->|untag packet|
>If you still want to go on, focus on the method "get_packet_type" of

I tried to look at ethernet.py.
Probably, If outer tag's ether type is 0x88a8, I will be able to pop both
tag using OFPActionPopVlan(ether.ETH_TYPE_8021AH) and
OFPActionPushVlan(ether.ETH_TYPE_8021Q).
But my packet's both ether type are 0x8100. So I can not pop both tag.
Do I understand correctly?
