Kalle Valo says:
====================
wireless-drivers-next patches for v5.17
First set of patches for v5.17. The biggest change is the iwlmei
driver for Intel's AMT devices. Also now WCN6855 support in ath11k
should be usable.
Major changes:
ath10k
* fetch (pre-)calibration data via nvmem subsystem
ath11k
* enable 802.11 power save mode in station mode for qca6390 and wcn6855
* trace log support
* proper board file detection for WCN6855 based on PCI ids
* BSS color change support
rtw88
* add debugfs file to force lowest basic rate
* add quirk to disable PCI ASPM on HP 250 G7 Notebook PC
mwifiex
* add quirk to disable deep sleep with certain hardware revision in
Surface Book 2 devices
iwlwifi
* add iwlmei driver for co-operating with Intel's Active Management
Technology (AMT) devices
* tag 'wireless-drivers-next-2021-12-07' of git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next: (87 commits)
