====================
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)
