No, I was only speaking about the default class. You have a filter that put
some packets in 4:200. The rest of the traffic goes to the default class
4:100. But the packets are immediatly dequeued in class 4:100 so the filters
attached to 4:100 are never checked. You can simulate a default class if you
add a u32 filter with src 0/0.
The default class is for unclassified packets.
