Hello! I deal with dynamic shaping and I discovered the "error/bug" of function tc. If I have a lot of embedded parts of the network, so at the eighth level classes instead of creating the next level is created root class. And on the output screen says "invalid argument". In kernel error log is message: htb tree is too deep => maximum depth is 8. (tree looks like this: parentid 1:0 - classid 1:1, parent 1:1 - classid 1:2, parentid 1:2 - classid 1:3, ..., parentid 1:7 classid 1:8 <--- now is problem) Please refer to the Appendices script, try to run it and see for yourself. Is there any solution to enable more levels of depth as the 8? (This value is hardcoded in the code of kernel or iproute2 - where?)
