On SoCs with dedicated RX and TX interrupts (all except MT7621 and MT7628) platform_get_irq() is called for the first IRQ (eth->irq[0]) but it is never used. Skip the first IRQ and reduce the IRQ-count to 2.

2025-06-23net: stmmac: lpc18xx: use plat_dat->phy_interfaceRussell King (Oracle)
lpc18xx uses plat_dat->mac_interface, despite wanting to validate the PHY interface. Checking the DT files (arch/arm/boot/dts/nxp/lpc/), none of them specify mac-mode which means mac_interface and phy_interface will be identical. mac_interface is only used when there is some kind of MII converter between the DesignWare MAC and PHY, and describes the interface mode that the DW MAC needs to use, whereas phy_interface describes the interface mode that the PHY uses. Noting that lpc18xx only supports MII and RMII interface modes, switch this glue driver to use plat_dat->phy_interface, and to mark that the mac_interface is not used, explicitly set it to PHY_INTERFACE_MODE_NA. The latter is safe as the only user of mac_interface for this platform would be in stmmac_check_pcs_mode(), which only checks for RGMII or SGMII.

clang gets a bit confused by the code in the qed_mfw_process_tlv_req and ends up spilling registers to the stack hundreds of times. When sanitizers are enabled, this can end up blowing the stack warning limit: drivers/net/ethernet/qlogic/qed/qed_mng_tlv.c:1244:5: error: stack frame size (1824) exceeds limit (1280) in 'qed_mfw_process_tlv_req' [-Werror,-Wframe-larger-than] Apparently the problem is the complexity of qed_mfw_update_tlvs() after inlining, and marking the four main branches of that function as noinline_for_stack makes this problem completely go away, the stack usage goes down to 100 bytes.

2025-06-21gve: add XDP_TX and XDP_REDIRECT support for DQ RDAJoshua Washington
This patch adds support for XDP_TX and XDP_REDIRECT for the DQ RDA queue format. To appropriately support transmission of XDP frames, a new pending packet type GVE_TX_PENDING_PACKET_DQO_XDP_FRAME is introduced for completion handling, as there was a previous assumption that completed packets would be SKBs. XDP_TX handling completes the basic XDP actions, so the feature is recorded accordingly. This patch also enables the ndo_xdp_xmit callback allowing DQ to handle XDP_REDIRECT packets originating from another interface. The XDP spinlock is moved to common TX ring fields so that it can be used in both GQ and DQ. Originally, it was in a section which was mutually exclusive for GQ and DQ. In summary, 3 XDP features are exposed for the DQ RDA queue format: 1) NETDEV_XDP_ACT_BASIC 2) NETDEV_XDP_ACT_NDO_XMIT 3) NETDEV_XDP_ACT_REDIRECT Note that XDP and header-data split are mutually exclusive for the time being due to lack of multi-buffer XDP support. This patch does not add support for the DQ QPL format. That is to come in a future patch series.

2025-06-21gve: refactor DQO TX methods to be more generic for XDPJoshua Washington
This patch performs various minor DQO TX datapath refactors in preparation for adding XDP_TX and XDP_REDIRECT support. The following refactors are performed: 1) gve_tx_fill_pkt_desc_dqo() relies on a SKB pointer to get whether checksum offloading should be enabled. This won't work for the XDP case, which does not have a SKB. This patch updates the method to use a boolean representing whether checksum offloading should be enabled directly. 2) gve_maybe_stop_dqo() contains some synchronization between the true TX head and the cached value, a synchronization which is common for XDP queues and normal netdev queues. However, that method is reserved for netdev TX queues. To avoid duplicate code, this logic is factored out into a new method, gve_has_tx_slots_available(). 3) gve_tx_update_tail() is added to update the TX tail, a functionality that will be common between normal TX and XDP TX codepaths.

2025-06-19net: stmmac: loongson1: get ls1b resource only onceRussell King (Oracle)
ls1b_dwmac_syscon_init() was getting the stmmac iomem resource to detect which GMAC block is being used. Move this to a separate setup() function that only runs at probe time, so it can sensibly behave with an unrecognised resource adress. Use this to set a MAC index (id) which is then used in place of testing the base address.

Provide a structure for match data rather than using the function pointer as match data. This allows stronger type-checking for the function itself, and allows extensions to the match data.

EN7581 SoC allows configuring the size and the number of buffers in hwfd payload queue for both QDMA0 and QDMA1. In order to reduce the required DRAM used for hwfd buffers queues and decrease the memory footprint, differentiate hwfd buffer size for QDMA0 and QDMA1 and reduce hwfd buffer size to 1KB for QDMA1 (WAN) while maintaining 2KB for QDMA0 (LAN).

2025-06-19mlxbf_gige: return EPROBE_DEFER if PHY IRQ is not availableDavid Thompson
The message "Error getting PHY irq. Use polling instead" is emitted when the mlxbf_gige driver is loaded by the kernel before the associated gpio-mlxbf driver, and thus the call to get the PHY IRQ fails since it is not yet available. The driver probe() must return -EPROBE_DEFER if acpi_dev_gpio_irq_get_by() returns the same.

2025-06-19net: lan743x: fix potential out-of-bounds write in ↵Alexey Kodanev
lan743x_ptp_io_event_clock_get() Before calling lan743x_ptp_io_event_clock_get(), the 'channel' value is checked against the maximum value of PCI11X1X_PTP_IO_MAX_CHANNELS(8). This seems correct and aligns with the PTP interrupt status register (PTP_INT_STS) specifications. However, lan743x_ptp_io_event_clock_get() writes to ptp->extts[] with only LAN743X_PTP_N_EXTTS(4) elements, using channel as an index: lan743x_ptp_io_event_clock_get(..., u8 channel,...) { ... /* Update Local timestamp */ extts = &ptp->extts[channel]; extts->ts.tv_sec = sec; ... } To avoid an out-of-bounds write and utilize all the supported GPIO inputs, set LAN743X_PTP_N_EXTTS to 8.

Allow mana ethtool get_link_ksettings operation to report the maximum speed supported by the SKU in mbps. The driver retrieves this information by issuing a HWC command to the hardware via mana_query_link_cfg(), which retrieves the SKU's maximum supported speed. These APIs when invoked on hardware that are older/do not support these APIs, the speed would be reported as UNKNOWN.
