12 daysnet: libwx: use request_irq for VF misc interruptJiawen Wu
Currently, request_threaded_irq() is used with a primary handler but a NULL threaded handler, while also setting the IRQF_ONESHOT flag. This specific combination triggers a WARNING since the commit aef30c8d569c ("genirq: Warn about using IRQF_ONESHOT without a threaded handler"). WARNING: kernel/irq/manage.c:1502 at __setup_irq+0x4fa/0x760 Fix the issue by switching to request_irq(), which is the appropriate interface or a non-threaded interrupt handler, and removing the unnecessary IRQF_ONESHOT flag.

12 daysnet: libwx: fix VF illegal register accessJiawen Wu
Register WX_CFG_PORT_ST is a PF restricted register. When a VF is initialized, attempting to read this register triggers an illegal register access, which lead to a system hang. When the device is VF, the bus function ID can be obtained directly from the PCI_FUNC(pdev->devfn).

2026-04-23net: txgbe: fix firmware version checkJiawen Wu
For the device SP, the firmware version is a 32-bit value where the lower 20 bits represent the base version number. And the customized firmware version populates the upper 12 bits with a specific identification number. For other devices AML 25G and 40G, the upper 12 bits of the firmware version is always non-zero, and they have other naming conventions. Only SP devices need to check this to tell if XPCS will work properly. So the judgement of MAC type is added here. And the original logic compared the entire 32-bit value against 0x20010, which caused the outdated base firmwares bypass the version check without a warning. Apply a mask 0xfffff to isolate the lower 20 bits for an accurate base version comparison.

This is the exact same thing as the 'alloc_obj()' version, only much smaller because there are a lot fewer users of the *alloc_flex() interface.

This was done entirely with mindless brute force, using git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' | xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/' to convert the new alloc_obj() users that had a simple GFP_KERNEL argument to just drop that argument. Note that due to the extreme simplicity of the scripting, any slightly more complex cases spread over multiple lines would not be triggered: they definitely exist, but this covers the vast bulk of the cases, and the resulting diff is also then easier to check automatically. For the same reason the 'flex' versions will be done as a separate conversion. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook <kees@kernel.org>

2025-11-05net: libwx: fix device bus LAN IDJiawen Wu
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.

2025-10-16net: txgbe: optimize the flow to setup PHY for AML devicesJiawen Wu
To adapt to new firmware for AML devices, the driver should send the "SET_LINK_CMD" to the firmware only once when switching PHY interface mode, and no longer needs to re-trigger PHY configuration based on the RX signal interrupt (TXGBE_GPIOBIT_3). In previous firmware versions, the PHY was configured only after receiving "SET_LINK_CMD", and might remain incomplete if the RX signal was lost. To handle this case, the driver used TXGBE_GPIOBIT_3 interrupt to resend the command. This workaround is no longer necessary with the new firmware. And the unknown link speed is permitted in the mailbox buffer.

2025-10-16net: txgbe: expend SW-FW mailbox buffer size to identify QSFP moduleJiawen Wu
Recent firmware updates introduce additional fields in the mailbox message to provide more information for identifying 40G and 100G QSFP modules. To accommodate these new fields, expand the mailbox buffer size by 4 bytes. Without this change, drivers built against the updated firmware cannot properly identify modules due to mismatched mailbox message lengths. The old firmware version that used the smaller mailbox buffer has never been publicly released, so there are no backward-compatibility concerns.

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.
