From: liuzhongzhu <liuzhongzhu@huawei.com>
Add the debugfs framework to the driver and create a debugfs
command interface for each device.
example command:
"echo queue info > cmd" Query the packet forwarding queue information.

Query the queue information of the current NIC
such as BD size, queue header and tail pointer.
This patch adds support for debugfs command:
echo queue info 1 > cmd
it can print queue config information...

All the Flow Director rules are stored in tcam blocks.
For each bit of tcam entry, the match value
depends on two input value(x, y).
debugfs command:
echo dump fd tcam > cmd

> This patchset adds support of debugfs to the HNS3 driver.

> Support has been added to query info related to below items:

> 2. Flow Director ("echo dump fd tcam > cmd")
> 3. TC config ("echo dump tc > cmd")
> 4. Transmit Module/Scheduler ("echo dump tm > cmd")

> V1-->V2:
> * Addressed the comments provided by Jakub Kicinski.
> 1. Removed the .rej files mistakenly made part of Flow Director patch.
> Link: https://lkml.org/lkml/2018/11/20/249
> 2. Added command summary in the cover letter
