From: Salil Mehta
Date: Fri Nov 09 2018 - 17:09:23 EST


From: liuzhongzhu <liuzhongzhu@xxxxxxxxxx>

This patch prints qos priority map information.

debugfs command:
echo dump qos pri map > cmd

Sample Command:
root@(none)# echo dump qos pri map > cmd
hns3 0000:7d:00.0: dump qos pri map
hns3 0000:7d:00.0: vlan_to_pri: 0x0
hns3 0000:7d:00.0: pri_0_to_tc: 0x0
hns3 0000:7d:00.0: pri_1_to_tc: 0x0
hns3 0000:7d:00.0: pri_2_to_tc: 0x0
hns3 0000:7d:00.0: pri_3_to_tc: 0x0
hns3 0000:7d:00.0: pri_4_to_tc: 0x0
hns3 0000:7d:00.0: pri_5_to_tc: 0x0
hns3 0000:7d:00.0: pri_6_to_tc: 0x0
hns3 0000:7d:00.0: pri_7_to_tc: 0x0
