Subject: [RFC net-next 9/9] net: hns3: Add "tm map" status information query function
Date: Sun, 2 Dec 2018 23:09:33 +0000 [thread overview]
Message-ID: <20181202230933.15560-10-salil.mehta@huawei.com> (raw)
In-Reply-To: <20181202230933.15560-1-salil.mehta@huawei.com>
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)#
