====================
wireless-next patches for v6.10

The third, and most likely the last, "new features" pull request for
v6.10 with changes both in stack and in drivers. In ath12k and rtw89
we disabled Wireless Extensions just like with iwlwifi earlier. Wi-Fi
7 devices will not support Wireless Extensions (WEXT) anymore so if
someone is still using the legacy WEXT interface it's time to switch
to nl80211 now!

We merged wireless into wireless-next as we decided not to send a
wireless pull request to v6.9 this late in the cycle. Also an
immutable branch with MHI subsystem was merged to get ath11k and
ath12k hibernation working.

Major changes:

mac80211/cfg80211
 * handle color change per link

mt76
 * mt7921 LED control
 * mt7925 EHT radiotap support
 * mt7920e PCI support

ath12k
 * debugfs support
 * dfs_simulate_radar debugfs file
 * disable Wireless Extensions
 * suspend and hibernation support
 * ACPI support
 * refactoring in preparation of multi-link support

ath11k
 * support hibernation (required changes in qrtr and MHI subsystems)
 * ieee80211-freq-limit Device Tree property support

ath10k
 * firmware-name Device Tree property support

rtw89
 * complete features of new WiFi 7 chip 8922AE including BT-coexistence
   and WoWLAN
 * use BIOS ACPI settings to set TX power and channels
 * disable Wireless Extensios on Wi-Fi 7 devices

iwlwifi
 * block_esr debugfs file
 * support again firmware API 90 (was reverted earlier)
 * provide channel survey information for Automatic Channel Selection (ACS)
