Subject[PATCH V2 net-next 6/6] net: hns3: Add "tm map" status information query function
Date
From: liuzhongzhu <liuzhongzhu@huawei.com>

This patch prints dcb register status information by module.

debugfs command:
root@(none)# echo dump tm map 100 > cmd
queue_id | qset_id | pri_id | tc_id
0100 | 0065 | 08 | 00
root@(none)#
