Multiqueue tun/tap interface

I am trying to understand how Multiqueue tuntap interface works. Following the instructions provided at: https://www.kernel.org/doc/Documentation/networking/tuntap.txt I was able to create multiple queues. However, I don't know how to check the queus status and where they are created. I tried: $ tc -s class show dev tap0 (where tap0 is my tap interface), I see around 255 queues, even for a single ioctl call with IFF_MULTI_QUEUE flag. So probably I am looking at the wrong place. Here is the snippet of the output of the above command: class mq :1 root Sent 4741 bytes 37 pkt (dropped 0, overlimits 0 requeues 0) backlog 0b 0p requeues 0 class mq :2 root Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0) backlog 0b 0p requeues 0 . . . class mq :ff root Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0) backlog 0b 0p requeues 0 class mq :100 root Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0) backlog 0b 0p requeues 0 Secondly, I am not sure how to steer packets to these queues based on some filter or classifier using TC or anyother tool.
