Subject: [PATCH V2 net-next 7/8] net: hns3: Add "qos prio map" info query function
Date: Thu, 22 Nov 2018 14:09:47 +0000 [thread overview]
Message-ID: <20181122140948.23504-8-salil.mehta@huawei.com> (raw)

From: liuzhongzhu <liuzhongzhu@huawei.com>
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
