Merge tag 'wireless-next-2025-01-17' of git://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-next
Kalle Valo says: ==================== wireless-next patches for v6.14 Most likely the last "new features" pull request for v6.14 and this is a bigger one. Multi-Link Operation (MLO) work continues both in stack in drivers. Few new devices supported and usual fixes all over. Major changes: cfg80211 * Emergency Preparedness Communication Services (EPCS) station mode support mac80211 * an option to filter a sta from being flushed * some support for RX Operating Mode Indication (OMI) power saving * support for adding and removing station links for MLO iwlwifi * new device ids * rework firmware error handling and restart rtw88 * RTL8812A: RFE type 2 support * LED support rtw89 * variant info to support RTL8922AE-VS mt76 * mt7996: single wiphy multiband support (preparation for MLO) * mt7996: support for more variants * mt792x: P2P_DEVICE support * mt7921u: TP-Link TXE50UH support ath12k * enable MLO for QCN9274 (although it seems to be broken with dual band devices) * MLO radar detection support * debugfs: transmit buffer OFDMA, AST entry and puncture stats * tag 'wireless-next-2025-01-17' of git://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-next: (322 commits) wifi: brcmfmac: fix NULL pointer dereference in brcmf_txfinalize() wifi: rtw88: add RTW88_LEDS depends on LEDS_CLASS to Kconfig wifi: wilc1000: unregister wiphy only after netdev registration wifi: cfg80211: adjust allocation of colocated AP data wifi: mac80211: fix memory leak in ieee80211_mgd_assoc_ml_reconf() wifi: ath12k: fix key cache handling wifi: ath12k: Fix uninitialized variable access in ath12k_mac_allocate() function wifi: ath12k: Remove ath12k_get_num_hw() helper function wifi: ath12k: Refactor the ath12k_hw get helper function argument wifi: ath12k: Refactor ath12k_hw set helper function argument wifi: mt76: mt7996: add implicit beamforming support for mt7992 wifi: mt76: mt7996: fix beacon command during disabling wifi: mt76: mt7996: fix ldpc setting wifi: mt76: mt7996: fix definition of tx descriptor wifi: mt76: connac: adjust phy capabilities based on band constraints wifi: mt76: mt7996: fix incorrect indexing of MIB FW event wifi: mt76: mt7996: fix HE Phy capability wifi: mt76: mt7996: fix the capability of reception of EHT MU PPDU wifi: mt76: mt7996: add max mpdu len capability wifi: mt76: mt7921: avoid undesired changes of the preset regulatory domain ... ==================== Link: https://patch.msgid.link/20250117203529.72D45C4CEDD@smtp.kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
