* net: txgbe: use phylink_pcs_change() to report PCS link change eventsRussell King (Oracle)2024-04-301-1/+1
| | | | | | | | | | | Use phylink_pcs_change() when reporting changes in PCS link state to phylink as the interrupts are informing us about changes to the PCS state.

* net: libwx: fix alloc msix vectors failedDuanqiang Wen2024-04-191-1/+1
| | | | | | | | | | | | | | | | 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.

* net: txgbe: fix to clear interrupt status after handling IRQJiawen Wu2024-03-051-0/+2
| | | | | | | | | | | | GPIO EOI is not set to clear interrupt status after handling the interrupt. It should be done in irq_chip->irq_ack, but this function is not called in handle_nested_irq().

* net: txgbe: use irq_domain for interrupt controllerJiawen Wu2024-01-279-54/+193
| | | | | | | | | | | In the current interrupt controller, the MAC interrupt acts as the parent interrupt in the GPIO IRQ chip.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
