====================
wireless-next patches for v6.8

The second features pull request for v6.8. A bigger one this time with
changes both to stack and drivers. We have a new Wifi band RFI (WBRF)
mitigation feature for which we pulled an immutable branch shared with
other subsystems. And, as always, other new features and bug fixes all
over.

Major changes:

cfg80211/mac80211
 * AMD ACPI based Wifi band RFI (WBRF) mitigation feature
 * Basic Service Set (BSS) usage reporting
 * TID to link mapping support
 * mac80211 hardware flag to disallow puncturing

iwlwifi
 * new debugfs file fw_dbg_clear

mt76
 * NVMEM EEPROM improvements
 * mt7996 Extremely High Throughpu (EHT) improvements
 * mt7996 Wireless Ethernet Dispatcher (WED) support
 * mt7996 36-bit DMA support

ath12k
 * support one MSI vector
 * WCN7850: support AP mode

* tag 'wireless-next-2023-12-18' of git://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-next: (207 commits)
  wifi: mt76: mt7996: Use DECLARE_FLEX_ARRAY() and fix -Warray-bounds warnings
  wifi: ath11k: workaround too long expansion sparse warnings
  Revert "wifi: ath12k: use ATH12K_PCI_IRQ_DP_OFFSET for DP IRQ"
  wifi: rt2x00: remove useless code in rt2x00queue_create_tx_descriptor()
  wifi: rtw89: only reset BB/RF for existing WiFi 6 chips while starting up
  wifi: rtw89: add DBCC H2C to notify firmware the status
  wifi: rtw89: mac: add suffix _ax to MAC functions
  wifi: rtw89: mac: add flags to check if CMAC and DMAC are enabled
  wifi: rtw89: 8922a: add power on/off functions
  wifi: rtw89: add XTAL SI for WiFi 7 chips
  wifi: rtw89: phy: print out RFK log with formatted string
  wifi: rtw89: parse and print out RFK log from C2H events
  wifi: rtw89: add C2H event handlers of RFK log and report
  wifi: rtw89: load RFK log format string from firmware file
  wifi: rtw89: fw: add version field to BB MCU firmware element
  wifi: rtw89: fw: load TX power track tables from fw_element
  wifi: mwifiex: configure BSSID consistently when starting AP
  wifi: mwifiex: add extra delay for firmware ready
  wifi: mac80211: sta_info.c: fix sentence grammar
  wifi: mac80211: rx.c: fix sentence grammar
  ...
