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) 0000 dwrr 100 0 0 0 5 20 0 0 150 7 0 5 20 0 0 0001 sp 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0002 sp 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0003 sp 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0004 sp 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0005 sp 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0006 sp 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0007 sp 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

From: Guangbin Huang huangguangbin2@huawei.com
In order to query tm info of nodes, priority and qset for debugging, adds three debugfs files tm_nodes, tm_priority and tm_qset in newly created tm directory.
Unlike previous debugfs commands, these three files just support read ops, so they only support to use cat command to dump their info.
The new tm file style is acccording to suggestion from Jakub Kicinski's opinion as link https://lkml.org/lkml/2020/9/29/2101.

In order to query tm info of nodes, priority and qset for debugging, adds three debugfs files tm_nodes, tm_priority and tm_qset in newly created tm directory.
Unlike previous debugfs commands, these three files just support read ops, so they only support to use cat command to dump their info.
The new tm file style is acccording to suggestion from Jakub Kicinski's opinion as link https://lkml.org/lkml/2020/9/29/2101.
