This patchset adds dump tm info of nodes, priority and qset in debugfs.
Three debugfs files tm_nodes, tm_priority and tm_qset are created in
new tm directory, and use cat command to dump their info, for examples:
$ cat tm_nodes
BASE_ID MAX_NUM
PG 0 8
PRI 0 8
QSET 0 8
QUEUE 0 1024
$ cat tm_priority
ID MODE DWRR C_IR_B C_IR_U C_IR_S C_BS_B C_BS_S C_FLAG C_RATE(Mbps)
P_IR_B P_IR_U P_IR_S P_BS_B P_BS_S P_FLAG P_RATE(Mbps)
