12 daysnet: airoha: Move net_devs registration in a dedicated routineLorenzo Bianconi
Since airoha_probe() is not executed under rtnl lock, there is small race where a given device is configured by user-space while the remaining ones are not completely loaded from the dts yet. This condition will allow a hw device misconfiguration since there are some conditions (e.g. GDM2 check in airoha_dev_init()) that require all device are properly loaded from the device tree. Fix the issue moving net_devices registration at the end of the airoha_probe routine.

2025-11-17net: airoha: Do not loopback traffic to GDM2 if it is available on the deviceLorenzo Bianconi
Airoha_eth driver forwards offloaded uplink traffic (packets received on GDM1 and forwarded to GDM{3,4}) to GDM2 in order to apply hw QoS. This is correct if the device does not support a dedicated GDM2 port. In this case, in order to enable hw offloading for uplink traffic, the packets should be sent to GDM{3,4} directly.

2025-11-07net: airoha: Add the capability to consume out-of-order DMA tx descriptorsLorenzo Bianconi
EN7581 and AN7583 SoCs are capable of DMA mapping non-linear tx skbs on non-consecutive DMA descriptors. This feature is useful when multiple flows are queued on the same hw tx queue since it allows to fully utilize the available tx DMA descriptors and to avoid the starvation of high-priority flow we have in the current codebase due to head-of-line blocking introduced by low-priority flows.

In order to avoid any possible race we need to hold the ppe_lock spinlock accessing the hw PPE table. airoha_ppe_foe_get_entry routine is always executed holding ppe_lock except in airoha_ppe_debugfs_foe_show routine. Fix the problem introducing airoha_ppe_foe_get_entry_locked routine.

2025-07-16net: airoha: fix potential use-after-free in airoha_npu_get()Alok Tiwari
np->name was being used after calling of_node_put(np), which releases the node and can lead to a use-after-free bug. Previously, of_node_put(np) was called unconditionally after of_find_device_by_node(np), which could result in a use-after-free if pdev is NULL. This patch moves of_node_put(np) after the error check to ensure the node is only released after both the error and success cases are handled appropriately, preventing potential resource issues.

2025-07-08net: Use of_reserved_mem_region_to_resource{_byname}() for "memory-region"Rob Herring (Arm)
Use the newly added of_reserved_mem_region_to_resource{_byname}() functions to handle "memory-region" properties. The error handling is a bit different for mtk_wed_mcu_load_firmware(). A failed match of the "memory-region-names" would skip the entry, but then other errors in the lookup and retrieval of the address would not skip the entry. However, that distinction is not really important. Either the region is available and usable or it is not. So now, errors from of_reserved_mem_region_to_resource() are ignored so the region is simply skipped.
