2024-05-07net: annotate writes on dev->mtu from ndo_change_mtu()Eric Dumazet
Simon reported that ndo_change_mtu() methods were never updated to use WRITE_ONCE(dev->mtu, new_mtu) as hinted in commit 501a90c94510 ("inet: protect against too small mtu values.") We read dev->mtu without holding RTNL in many places, with READ_ONCE() annotations. It is time to take care of ndo_change_mtu() methods to use corresponding WRITE_ONCE() Signed-off-by: Eric Dumazet <edumazet@google.com> Reported-by: Simon Horman <horms@kernel.org> Closes: https://lore.kernel.org/netdev/20240505144608.GB67882@kernel.org/ Reviewed-by: Jacob Keller <jacob.e.keller@intel.com> Reviewed-by: Sabrina Dubroca <sd@queasysnail.net> Reviewed-by: Simon Horman <horms@kernel.org> Acked-by: Shannon Nelson <shannon.nelson@amd.com> Link: https://lore.kernel.org/r/20240506102812.3025432-1-edumazet@google.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2024-04-19net: libwx: fix alloc msix vectors failedDuanqiang Wen
driver needs queue msix vectors and one misc irq vector, but only queue vectors need irq affinity. when num_online_cpus is less than chip max msix vectors, driver will acquire (num_online_cpus + 1) vecotrs, and call pci_alloc_irq_vectors_affinity functions with affinity params without setting pre_vectors or post_vectors, it will cause return error code -ENOSPC. Misc irq vector is vector 0, driver need to set affinity params .pre_vectors = 1.

2024-01-27net: txgbe: use irq_domain for interrupt controllerJiawen Wu
In the current interrupt controller, the MAC interrupt acts as the parent interrupt in the GPIO IRQ chip. But when the number of Rx/Tx ring changes, the PCI IRQ vector needs to be reallocated. Then this interrupt controller would be corrupted. So use irq_domain structure to avoid the above problem. Signed-off-by: Jiawen Wu <jiawenwu@trustnetic.com> Signed-off-by: David S.

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.
