Subject: [PATCH V2 net-next 0/8] net: hns3: Adds support of debugfs to HNS3 driver

This patchset adds support of debugfs to the HNS3 driver. 

Support has been added to query info related to below items:
1. Queue related ("echo queue info [queue no] > cmd")
2. Flow Director ("echo dump fd tcam > cmd")
3. TC config ("echo dump tc > cmd")
4. Transmit Module/Scheduler ("echo dump tm > cmd")
5. QoS pause ("echo dump qos pause cfg > cmd")
6. QoS buffer ("echo dump qos pri map > cmd")
7. QoS prio map ("echo dump qos buf cfg > cmd")

NOTE: Above commands are *read-only* and are only intended to
query the information from the SoC(and dump inside the kernel,
for now) and in no way tries to perform write operations for
the purpose of configuration etc.
