2023-07-18net: txgbe: change LAN reset modeJiawen Wu
The old way to do LAN reset is sending reset command to firmware. Once firmware performs reset, it reconfigures what it needs. In the new firmware versions, veto bit is introduced for NCSI/LLDP to block PHY domain in LAN reset. At this point, writing register of LAN reset directly makes the same effect as the old way. And it does not reset MNG domain, so that veto bit does not change. Since veto bit was never used, the old firmware is compatible with the driver before and after this change. The new firmware needs to use with the driver after this change if it wants to implement the new feature, otherwise it is the same as the old firmware.

2023-06-07net: txgbe: Avoid passing uninitialised parameter to pci_wake_from_d3()Simon Horman
txgbe_shutdown() relies on txgbe_dev_shutdown() to initialise wake by passing it by reference. However, txgbe_dev_shutdown() doesn't use this parameter at all. wake is then passed uninitialised by txgbe_dev_shutdown() to pci_wake_from_d3(). Resolve this problem by: * Removing the unused parameter from txgbe_dev_shutdown() * Removing the uninitialised variable wake from txgbe_dev_shutdown() * Passing false to pci_wake_from_d3() - this assumes that although uninitialised wake was in practice false (0). I'm not sure that this counts as a bug, as I'm not sure that it manifests in any unwanted behaviour. But in any case, the issue was introduced by: 3ce7547e5b71 ("net: txgbe: Add build support for txgbe") Flagged by Smatch as: .../txgbe_main.c:486 txgbe_shutdown() error: uninitialized symbol 'wake'.

pci_enable_pcie_error_reporting() enables the device to send ERR_* Messages. Since f26e58bf6f54 ("PCI/AER: Enable error reporting when AER is native"), the PCI core does this for all devices during enumeration, so the driver doesn't need to do it itself. Remove the redundant pci_enable_pcie_error_reporting() call from the driver. Also remove the corresponding pci_disable_pcie_error_reporting() from the driver .remove() path. Note that this only controls ERR_* Messages from the device. An ERR_* Message may cause the Root Port to generate an interrupt, depending on the AER Root Error Command register managed by the AER service driver.
