Subject: [RFC net-next 0/9] net: hns3: Add more commands to Debugfs in HNS3 driver

This patch-set adds few more debugfs commands to HNS3 Ethernet
Driver. Support has been added to query info related to below
items:
1. Packet buffer descriptor ("echo bd info [queue no] [bd index] > cmd")
2. Mac Forward table("echo dump mac tbl > cmd")
3. Port vlan Forward table("echo dump port vlan tbl > cmd")
4. Vf vlan Forward table("echo dump vf vlan tbl [vf id]> cmd")
5. Manager table("echo dump mng tbl > cmd")
6. Dfx status register("echo dump reg ssu [prt id] > cmd")
7. Dcb status register("echo dump reg dcb [port id] > cmd")
8. Queue map ("echo queue map [queue no] > cmd")
9. Tm map ("echo tm map [queue no] > 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.

As per the earlier community review, it was understood that any
attempt to add commands for which standard tools are present is
discouraged. Any review comments and suggestions related to above
set of commands would be of great help in preapring the final
patch-set. Thank you!
