Subject: [PATCH V6 00/10] wifi: ath12k: add MU-MIMO and 160 MHz bandwidth support

Add support for
1. enabling MU-MIMO in HE and EHT modes from hardware
2. setting fixed HE rate/GI/LTF
3. 160 MHz bandwidth in HE mode
4. extended NSS bandwidth support

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3

changes in v6:
- Change comment in patch 01/10 to represent only AP mode
implementation.

changes in v5:
- Fix column length to 80 in patch 01/10
- Fix advertises spelling in patch 09/10
- Fix choosing spelling in patch 10/10

changes in v4:
- Fix ath12k-check warnings in patch 2/10 and 7/10
- remove "hostapd" reference in patches 2/10 and 3/10
- remove redundant prerequisite-patch-id's in cover letter

changes in v3:
- address review comments for fixing ath12k-check issues.

changes in v2:
- Amend mac80211 patch description as the patch is not specific
to AP mode.
- Amend EHT MU-MIMO patch description to specify future support
for STA mode.

Subject: [PATCH V6 03/10] wifi: ath12k: push EHT MU-MIMO params to hardware

Currently, only the EHT IE in management frames is updated with
respect to MU-MIMO configurations, but this change is not
reflected in the hardware. Add support to propagate MU-MIMO
configurations to the hardware as well for AP mode. Similar
support for STA mode will be added in future.

Subject: [PATCH V6 01/10] wifi: mac80211: Add EHT UL MU-MIMO flag in ieee80211_bss_conf

Add flag for Full Bandwidth UL MU-MIMO for EHT. This is utilized
to pass EHT MU-MIMO configurations from user space to driver
in AP mode.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1

Subject: [PATCH V6 07/10] wifi: ath12k: add support for setting fixed HE rate/GI/LTF

Add support to set fixed HE rate/GI/LTF values using nl80211.
Reuse parts of the existing code path already used for HT/VHT
to implement the new helpers symmetrically, similar to how
HT/VHT is handled.

Subject: [PATCH V6 02/10] wifi: ath12k: push HE MU-MIMO params to hardware

Currently, only the HE IE in management frames is updated with
respect to MU-MIMO configurations, but this change is not
reflected in the hardware. Add support to propagate MU-MIMO
configurations to the hardware as well.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
