2025-11-24wifi: mt76: Introduce the NPU generic layerLorenzo Bianconi
Add the NPU generic layer in mt76 module. NPU will be used to enable traffic forward offloading between the MT76 NIC and the Airoha ethernet one available on the Airoha EN7581 SoC using Netfilter Flowtable APIs.

2025-11-24wifi: mt76: relicense to BSD-3-Clause-ClearFelix Fietkau
MediaTek has asked to switch from the ISC license to BSD-3-Clause-Clear, in order to improve clarity and the legal integrity of the code. 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 GPL 2.0 remains in use on mt76x0, as well as two source files in mt7615 for which the license situation still needs to be clarified.

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.

2025-06-24wifi: cfg80211/mac80211: Add support to get radio indexRoopni Devanathan
Currently, per-radio attributes are set on per-phy basis, i.e., all the radios present in a wiphy will take attributes values sent from user. But each radio in a wiphy can get different values from userspace based on its requirement. To extend support to set per-radio attributes, add support to get radio index from userspace. Add an NL attribute - NL80211_ATTR_WIPHY_RADIO_INDEX, to get user specified radio index for which attributes should be changed. Pass this to individual drivers, so that the drivers can use this radio index to change per-radio attributes when necessary. Currently, per-radio attributes identified are: NL80211_ATTR_WIPHY_TX_POWER_LEVEL NL80211_ATTR_WIPHY_ANTENNA_TX NL80211_ATTR_WIPHY_ANTENNA_RX NL80211_ATTR_WIPHY_RETRY_SHORT NL80211_ATTR_WIPHY_RETRY_LONG NL80211_ATTR_WIPHY_FRAG_THRESHOLD NL80211_ATTR_WIPHY_RTS_THRESHOLD NL80211_ATTR_WIPHY_COVERAGE_CLASS NL80211_ATTR_TXQ_LIMIT NL80211_ATTR_TXQ_MEMORY_LIMIT NL80211_ATTR_TXQ_QUANTUM By default, the radio index is set to -1. This means the attribute should be treated as a global configuration. If the user has not specified any index, then the radio index passed to individual drivers would be -1. This would indicate that the attribute applies to all radios in that wiphy.
