net: libwx: fix device bus LAN ID

2025-11-06T01:52:13Z

The device bus LAN ID was obtained from PCI_FUNC(), but when a PF port is passthrough to a virtual machine, the function number may not match the actual port index on the device. This could cause the driver to perform operations such as LAN reset on the wrong port. Fix this by reading the LAN ID from port status register.

net: libwx: restrict change user-set RSS configuration

2025-09-30T01:11:16Z

Enable/disable SR-IOV 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. Signed-off-by: Jiawen Wu Link: https://patch.msgid.link/20250926023843.34340-5-jiawenwu@trustnetic.com Signed-off-by: Jakub Kicinski

net: wangxun: add RSS reta and rxfh fields support

2025-09-30T01:11:16Z

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.

net: libwx: move rss_field to struct wx

2025-09-30T01:11:16Z

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.

net: libwx: support separate RSS configuration for every pool

2025-09-30T01:11:16Z

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.

net: libwx: fix to enable RSS

2025-09-04T20:34:01Z

Now when SRIOV is enabled, PF with multiple queues can only receive all packets on queue 0. This is caused by an incorrect flag judgement, which prevents RSS from being enabled. In fact, RSS is supported for the functions when SRIOV is enabled. Remove the flag judgement to fix it.
