====================
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

+  Qualcomm Technologies IEEE 802.11be PCIe devices with WSI interface.
+
+  The ath12k devices (QCN9274) feature WSI support. WSI stands for
+  WLAN Serial Interface. It is used for the exchange of specific
+  control information across radios based on the doorbell mechanism.
+  This WSI connection is essential to exchange control information
+  among these devices.
+
+  The WSI interface includes TX and RX ports, which are used to connect
+  multiple WSI-supported devices together, forming a WSI group.
+
+  Diagram to represent one WSI connection (one WSI group) among
+  three devices.
