2026-02-10net: ethernet: marvell: skge: remove incorrect conflicting PCI IDEthan Nelson-Moore
The ID 1186:4302 is matched by both r8169 and skge. The same device ID should not be in more than one driver, because in that case, which driver is used is unpredictable. I downloaded the latest drivers for all hardware revisions of the D-Link DGE-530T from D-Link's website, and the only drivers which contain this ID are Realtek drivers. Therefore, remove this device ID from skge. In the kernel bug report which requested addition of this device ID, someone created a patch to add the ID to skge. Then, it was pointed out that this device is an "r8169 in disguise", and a patch was created to add it to r8169. Somehow, both of these patches got merged. See the link below.

2026-02-05octeontx2-af: Fix PF driver crash with kexec kernel bootingAnshumali Gaur
During a kexec reboot the hardware is not power-cycled, so AF state from the old kernel can persist into the new kernel. When AF and PF drivers are built as modules, the PF driver may probe before AF reinitializes the hardware. The PF driver treats the RVUM block revision as an indication that AF initialization is complete. If this value is left uncleared at shutdown, PF may incorrectly assume AF is ready and access stale hardware state, leading to a crash. Clear the RVUM block revision during AF shutdown to avoid PF mis-detecting AF readiness after kexec.

NIX SQ manager sticky mode is known to cause stalls when multiple SQs share an SMQ and transmit concurrently. Additionally, PSE may deadlock on transitions between sticky and non-sticky transmissions. There is also a credit drop issue observed when certain condition clocks are gated. work around these hardware errata by: - Disabling SQM sticky operation: - Clear TM6 (bit 15) - Clear TM11 (bit 14) - Disabling sticky → non-sticky transition path that can deadlock PSE: - Clear TM5 (bit 23) - Preventing credit drops by keeping the control-flow clock enabled: - Set TM9 (bit 21) These changes are applied via NIX_AF_SQM_DBG_CTL_STATUS. With this configuration the SQM/PSE maintain forward progress under load without credit loss, at the cost of disabling sticky optimizations.

2026-01-25net: mvpp2: cls: Fix memory leak in mvpp2_ethtool_cls_rule_ins()Zilin Guan
In mvpp2_ethtool_cls_rule_ins(), the ethtool_rule is allocated by ethtool_rx_flow_rule_create(). If the subsequent conversion to flow type fails, the function jumps to the clean_rule label. However, the clean_rule label only frees efs, skipping the cleanup of ethtool_rule, which leads to a memory leak. Fix this by jumping to the clean_eth_rule label, which properly calls ethtool_rx_flow_rule_destroy() before freeing efs. Compile tested only.

octep_vf_request_irqs() requests MSI-X queue IRQs with dev_id set to ioq_vector. If request_irq() fails part-way, the rollback loop calls free_irq() with dev_id set to 'oct', which does not match the original dev_id and may leave the irqaction registered.

prestera_ldr_wait_buf() returns the result of readl_poll_timeout(), which is 0 on success or -ETIMEDOUT on failure. Its current return type is u32. Assigning this u32 value to an int variable works today because the bit pattern of (u32)-ETIMEDOUT (0xffffff92) is correctly interpreted as -ETIMEDOUT when stored in an int. However, keeping the function return type as u32 is misleading and fragile.

Allow devlink_param::get() handlers to report error messages via extack. This function is called in a few different contexts, but not all of them will have an valid extack to use. When devlink_param::get() is called from param_get_doit or param_get_dumpit contexts, pass the extack through so that drivers can report errors when retrieving param values. devlink_param::get() is called from the context of devlink_param_notify(), pass NULL in for the extack.

2025-11-19octeontx2-af: Skip TM tree print for disabled SQsAnshumali Gaur
Currently, the TM tree is printing all SQ topology including those which are not enabled, this results in redundant output for SQs which are not active. This patch adds a check in print_tm_tree() to skip printing the TM tree hierarchy if the SQ is not enabled.
