net: txgbe: remove the redundant data return in SW-FW mailbox

2026-01-30T09:32:26Z

commit 3d778e65b4f44c6af4901d83020bb8a0a010f39e upstream. For these two firmware mailbox commands, in txgbe_test_hostif() and txgbe_set_phy_link_hostif(), there is no need to read data from the buffer. Under the current setting, OEM firmware will cause the driver to fail to probe. Because OEM firmware returns more link information, with a larger OEM structure txgbe_hic_ephy_getlink. However, the current driver does not support the OEM function. So just fix it in the way that does not involve reading the returned data.

net: wangxun: move PHYLINK dependency

[ Upstream commit b94f11af9d9201426f4d6c8a753493fd58d6ac16 ] The LIBWX library code is what calls into phylink, so any user of it has to select CONFIG_PHYLINK at the moment, with NGBEVF missing this: x86_64-linux-ld: drivers/net/ethernet/wangxun/libwx/wx_ethtool.o: in function `wx_nway_reset': wx_ethtool.c:(.text+0x613): undefined reference to `phylink_ethtool_nway_reset' x86_64-linux-ld: drivers/net/ethernet/wangxun/libwx/wx_ethtool.o: in function `wx_get_link_ksettings': wx_ethtool.c:(.text+0x62b): undefined reference to `phylink_ethtool_ksettings_get' x86_64-linux-ld: drivers/net/ethernet/wangxun/libwx/wx_ethtool.o: in function `wx_set_link_ksettings': wx_ethtool.c:(.text+0x643): undefined reference to `phylink_ethtool_ksettings_set' x86_64-linux-ld: drivers/net/ethernet/wangxun/libwx/wx_ethtool.o: in function `wx_get_pauseparam': wx_ethtool.c:(.text+0x65b): undefined reference to `phylink_ethtool_get_pauseparam' x86_64-linux-ld: drivers/net/ethernet/wangxun/libwx/wx_ethtool.o: in function `wx_set_pauseparam': wx_ethtool.c:(.text+0x677): undefined reference to `phylink_ethtool_set_pauseparam' Add the 'select PHYLINK' line in the libwx option directly so this will always be enabled for all current and future wangxun drivers, and remove the now duplicate lines.

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: 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.
