Hello. Current ixgbe driver lacks of Q-in-Q support for the 82599 controller. As result, all double tagged frames are processed in the NIC's first queue.
I've tried to follow Steve O'Brien's tips from this message: http://sourceforge.net/p/e1000/mailman/message/31380074/ using patch in attachment, which sets up bits in the followings registers: - DMATXCTL.GDV - CTRL_EXT.Extended VLAN I didn't try to modify EXVET.VETEXT register, it's default value 0x8100 is fine for me. After all tries I had no luck - traffic is still going to the first queue.
