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

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

[Salil Mehta]

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!

[RFC net-next 6/9] net: hns3: Add "status register" information query function

[Salil Mehta]

From: liuzhongzhu <liuzhongzhu@huawei.com>

This patch prints status register information by module.

debugfs command:
echo dump reg [mode name] > cmd

Sample Command:
root@(none)# echo dump reg bios common > cmd
 BP_CPU_STATE: 0x0
 DFX_MSIX_INFO_NIC_0: 0xc000
 DFX_MSIX_INFO_NIC_1: 0xf
 DFX_MSIX_INFO_NIC_2: 0x2
 DFX_MSIX_INFO_NIC_3: 0x2
 DFX_MSIX_INFO_ROC_0: 0xc000
 DFX_MSIX_INFO_ROC_1: 0x0
 DFX_MSIX_INFO_ROC_2: 0x0
 DFX_MSIX_INFO_ROC_3: 0x0
root@(none)#

Adding debugfs files for basic switch concepts like MAC and VLAN tables
seems like a bit of a stretch to me.  I wonder what others think.

I was wondering how other vendors are solving this? One way I could 
understand is to use "Switchdev" framework which in turn will expose
entries to the kernel using the switch driver. In our NIC we don't
have a proper switch and it cannot learn/age entries.

Also, on-SoC NIC contains other tables which might not have any standard
user-space interface at all. What are your suggestions regarding that?


Thanks

Your hardware is there to accelerate what linux can do in software.
How do we manage the software version of this feature?

How are these tables map to software features the Linux stack
implements?

Yes, so it can kind of represent switch in the hardware, has vports and has
tables for mac-vlan, port-vlan, vlan (which I guess kernel also supports in
vlan aware mode of bridging?). Perhaps, only way I can understand now to be
able to use standard bridge, ip link tools to fetch this info is by having
represented them by "Switchdev"?

If you refer output shown in patch you will get an idea, 
[RFC net-next 5/9] net: hns3: Add "manager table" information query function

Manager Table stores entries for any exception packet matching or for matching
any special types like control packets which we might not want to forward
using general forwarding route using mac-vlan table.

Not sure if this makes sense inside Linux kernel? Therefore, we thought of
exposing them through the debugfs.
