[PATCH net-next v5 0/4] net: wangxun: support to configure RSS

[PATCH net-next v5 0/4] net: wangxun: support to configure RSS

[Jiawen Wu]

Implement ethtool ops for RSS configuration, and support multiple RSS
for multiple pools.

---
v5:
- add a separate patch for moving rss_field to struct wx
- add a patch to restrict change number of ring
- rename "random_key_size"
- use wx->rss_key[i] instead of *(wx->rss_key + i)

v4:
- rebase on net-next

v3: https://lore.kernel.org/all/20250902032359.9768-1-jiawenwu@trustnetic.com/
- remove the redundant check of .set_rxfh
- add a dependance of the new fix patch

v2: https://lore.kernel.org/all/20250829091752.24436-1-jiawenwu@trustnetic.com/
- embed iterator declarations inside the loop declarations
- replace int with u32 for the number of queues
- add space before '}'
- replace the offset with FIELD_PREP()

v1: https://lore.kernel.org/all/20250827064634.18436-1-jiawenwu@trustnetic.com/

[PATCH net-next v5 1/4] net: libwx: support separate RSS configuration for every pool

[Jiawen Wu]

For those devices which support 64 pools, they also support PF and VF
(i.e. different pools) to configure different RSS key and hash table.
Enable multiple RSS, use up to 64 RSS configurations and each pool has a
specific configuration.

[PATCH net-next v5 2/4] net: libwx: move rss_field to struct wx

[Jiawen Wu]

For global RSS and multiple RSS scheme, the RSS type fields are defined
identically in the registers. So they can be defined as the macros
WX_RSS_FIELD_* to cleanup the codes. And to prepare for the RXFH support
in the next patch, move the rss_field to struct wx.

[PATCH net-next v5 3/4] net: wangxun: add RSS reta and rxfh fields support

[Jiawen Wu]

Add ethtool ops for Rx flow hashing, query and set RSS indirection table
and hash key. Disable UDP RSS by default, and support to configure L4
header fields with TCP/UDP/SCTP for flow hasing.

[PATCH net-next v5 4/4] net: libwx: restrict change user-set RSS configuration

[Jiawen Wu]

Enable/disable SR-IOV and use ethtool to set channels will change the
number of rings, thereby changing the RSS configuration that the user has
set.

So reject these attempts if netif_is_rxfh_configured() returns true. And
remind the user to reset the RSS configuration.

Why the check in set_channels? Kernel already rejects attempts to
decrease queue count below what's configured in the indir table.
If table is set you should be able to change the ring count, just
don't override the table.

There is a few tests for the RSS API in the tree:

tools/testing/selftests/drivers/net/hw/rss_api.py
tools/testing/selftests/drivers/net/hw/rss_ctx.py

Please run these and add the output to the cover letter.

Instructions for running the tests are here:

The output shows many fail cases. Is it normal? Or is there some issue
with my environment?

It's most;u normal, the test don't check capabilities so if you don't
support a feature the test case will fail.

Thanks, this iperf3 test is passed.
I'll paste the output in the v6 cover-letter.
