Subject: [iproute2] tc: Show classes more hierarchically]

Hi All,

I am playing with showing classes in more hierarchically format and I
have some code and example of output from my TC looks like:

# tc/tc -t class show dev tap0

 \---1:2 (htb) prio 0 rate 1Kbit ceil 6Mbit burst 15Kb cburst 1599b 
        \---1:40 (htb) prio 0 rate 1Kbit ceil 6Mbit burst 15Kb cburst 1599b 
        \---1:50 (htb) prio 0 rate 1Kbit ceil 6Mbit burst 15Kb cburst 1599b 
        \---1:60 (htb) prio 0 rate 1Kbit ceil 6Mbit burst 15Kb cburst 1599b 
 \---1:1 (htb) prio 0 rate 1Kbit ceil 6Mbit burst 15Kb cburst 1599b 
        \---1:10 (htb) prio 0 rate 1Kbit ceil 6Mbit burst 15Kb cburst 1599b 
               \---1:11 (htb) prio 0 rate 1Kbit ceil 6Mbit burst 15Kb cburst 1599b 
                      \---1:111 (htb) prio 0 rate 1Kbit ceil 6Mbit burst 15Kb cburst 1599b 
        \---1:20 (htb) prio 0 rate 1Kbit ceil 6Mbit burst 15Kb cburst 1599b 
        \---1:30 (htb) prio 0 rate 1Kbit ceil 6Mbit burst 15Kb cburst 1599b 


which in standart output mode it looks like:

# tc/tc class show dev tap0

class htb 1:11 parent 1:10 rate 3Mbit ceil 6Mbit burst 15Kb cburst 1599b 
class htb 1:111 parent 1:11 prio 0 rate 1Kbit ceil 6Mbit burst 15Kb cburst 1599b 
class htb 1:10 parent 1:1 rate 5Mbit ceil 5Mbit burst 15Kb cburst 1600b 
class htb 1:1 root rate 6Mbit ceil 6Mbit burst 15Kb cburst 1599b 
class htb 1:20 parent 1:1 leaf 20: prio 0 rate 3Mbit ceil 6Mbit burst 15Kb cburst 1599b 
class htb 1:2 root rate 6Mbit ceil 6Mbit burst 15Kb cburst 1599b 
class htb 1:30 parent 1:1 leaf 30: prio 0 rate 1Kbit ceil 6Mbit burst 15Kb cburst 1599b 
class htb 1:40 parent 1:2 leaf 40: prio 0 rate 5Mbit ceil 5Mbit burst 15Kb cburst 1600b 
class htb 1:50 parent 1:2 leaf 50: prio 0 rate 3Mbit ceil 6Mbit burst 15Kb cburst 1599b 
class htb 1:60 parent 1:2 leaf 60: prio 0 rate 1Kbit ceil 6Mbit burst 15Kb cburst 1599b 

So I'd like to ask if it might be useful for the TC users (may be
better format ?) to have this ?

Thanks,
