2025-11-24wifi: mt76: mt7996: fix MLO set key and group key issuesShayne Chen
This patch fixes the following key issues: - Pass correct link BSS to mt7996_mcu_add_key(), and use HW beacon protection mode for mt7990 chipset - Do not do group key deletion for GTK and IGTK due to FW design, the delete key command will delete all group keys of a link BSS - For deleting BIGTK, FW adds a new flow, but the "sec->add" field should be filled with "SET_KEY". Note that if BIGTK is not deleted, it will cause beacon decryption issue when switching from an AP interface to a station interface Fixes: 0c45d52276fd ("wifi: mt76: mt7996: fix setting beacon protection keys") Co-developed-by: Allen Ye <allen.ye@mediatek.com> Signed-off-by: Allen Ye <allen.ye@mediatek.com> Co-developed-by: Peter Chiu <chui-hao.chiu@mediatek.com> Signed-off-by: Peter Chiu <chui-hao.chiu@mediatek.com> Signed-off-by: Shayne Chen <shayne.chen@mediatek.com> Link: https://patch.msgid.link/20251106064203.1000505-10-shayne.chen@mediatek.com Signed-off-by: Felix Fietkau <nbd@nbd.name>

2025-11-24wifi: mt76: replace use of system_wq with system_percpu_wqMarco Crivellari
Currently if a user enqueue a work item using schedule_delayed_work() the used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to schedule_work() that is using system_wq and queue_work(), that makes use again of WORK_CPU_UNBOUND. This lack of consistentcy cannot be addressed without refactoring the API. For more details see the Link tag below. This continues the effort to refactor workqueue APIs, which began with the introduction of new workqueues and a new alloc_workqueue flag in: commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq") commit 930c2ea566af ("workqueue: Add new WQ_PERCPU flag") Switch to using system_percpu_wq because system_wq is going away as part of a workqueue restructuring.

2025-11-24wifi: mt76: adjust BSS conf pointer handlingFedor Pchelkin
Passing a BSS conf pointer to mt76_connac2_mac_tx_rate_val() currently has two inconsistencies. When called from mt76_connac2_mac_write_txwi(), BSS conf is got by dereferencing a vif pointer. A NULL vif isn't accounted for though the function itself supposes it to be NULL and tries to handle this case in previous checks. This looks like a cosmetic change since the drivers calling the function (namely, mt7915 and mt7921) set WANT_MONITOR_VIF flag so judging by info->control.vif initialization inside ieee80211_tx_*() routines it can't actually come as NULL here. The same holds for the BSS conf pointer handling inside mt76_connac2_mac_tx_rate_val(). It is dereferenced before being checked for NULL. The function supposes to handle the case so reorder the check and dereference of the pointer. Again, this looks like a syntax issue only.

2025-11-24wifi: mt76: mmio_*_copy fix byte order and alignmentCaleb James DeLisle
Update functions which copy to and from MMIO to load bytes as Little Endian, and also support unaligned buffers. PCI devices almost universally use Little Endian ordering for MMIO registers, mt76 is no exception. PCI hardware that is designed to work with Big Endian CPUs often (but not always) "helps" by transparently byte-swapping MMIO reads and writes on the wire. If this is enabled then it cannot be turned off for a single write. On hardware which does not support this, writel() does the swap in software. When we are transferring arbitrary bytes to MMIO space, we need them to arrive in the same order they were in memory, so when the hardware swaps them this is a problem. Rather than care about how our PCI host controller works, we instead load bytes as Little Endian - so on a Big Endian machine this will reverse them, then we use writel() which will put them back in the right order again. This way we do not make it our business whether the swapping is done in software or hardware. Furthermore, inspection of the code shows that these functions are often called with stack-allocated u8 arrays which have no alignment guarantees so we now use (get|put)_unaligned_le32().

The BSD-3-Clause license includes the "no endorsement" clause, which is important for protecting the reputation of the original authors and contributors by preventing unauthorized use of their names for endorsement purposes. This clause is absent in the BSD-2-Clause license, which is more permissive but lacks this specific protection. This change also cleans up the license of some Kconfig/Makefile files, which were accidentally marked as GPL.

The commit 22b980badc0f ("mt76: add functions for parsing rate power limits from DT") introduced generic support for rates limits in the devicetree. But the mt7915 supports beamforming and has another table for configuring the backoff limits. These can be configured in the DT with the paths-* properties. The path-*-bf are the ones relevant for beamforming and the ones without -bf suffix for "traditional" path backoff.

The power-limits for ru and mcs and stored in the devicetree as bytewise array (often with sizes which are not a multiple of 4). These arrays have a prefix which defines for how many modes a line is applied. This prefix is also only a byte - but the code still tried to fix the endianness of this byte with a be32 operation. As result, loading was mostly failing or was sending completely unexpected values to the firmware. Since the other rates are also stored in the devicetree as bytewise arrays, just drop the u32 access + be32_to_cpu conversion and directly access them as bytes arrays.

2025-11-21net: stmmac: qcom-ethqos: use u32 for rgmii read/write/updateRussell King (Oracle)
readl() returns a u32, and writel() takes a "u32" for the value. These are used in rgmii_readl()() and rgmii_writel(), but the value and return are "int". As these are 32-bit register values which are not signed, use "u32". These changes do not cause generated code changes. Update rgmii_updatel() to use u32 for mask and val. Changing "mask" to "u32" also does not cause generated code changes. However, changing "val" causes the generated assembly to be re-ordered for aarch64. Update the temporary variables used with the rgmii functions to use u32.

2025-11-21wifi: rtl8xxxu: Enable 40 MHz width by defaultBitterblue Smith
40 MHz support is hidden behind the ht40_2g module parameter with this comment: /* * Some APs will negotiate HT20_40 in a noisy environment leading * to miserable performance. Rather than defaulting to this, only * enable it if explicitly requested at module load time. */ This parameter was added in commit 26f1fad29ad9 ("New driver: rtl8xxxu (mac80211)"). Back then rtl8xxxu only supported RTL8723AU and the RTL8192CU family. It's entirely possible the miserable performance was due to mistakes in the channel switching function, which were fixed in a previous patch. Delete the ht40_2g module parameter. If someone still needs to disable 40 MHz support, cfg80211 has the module parameter cfg80211_disable_40mhz_24ghz. That works too.
