Message

Pradeep Kumar Chitrapu Jan. 14, 2025, 12:38 a.m. UTC

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 v9: rebase on top of master branch with mlo changes
	patch 1/9 and 2/9:
	  - fetch link_conf using ath12k_mac_get_link_bss_conf()
	    instead of arvif->vif->bss_conf before mlo
	patch 6/9
	  - fetch mcs/nss values from sta->link[] instead of sta->deflink
	  - fix spelling of 'incompatibility'
	patch 8/9
	  - replace sta->deflink.addr with arsta->addr in
	    ath12k_peer_assoc_h_vht
	patch 9/9
	  - replace sta->deflink.rx_nss with link_sta->rx_nss

changes in v8:
 - rebase and resolve KASAN warnings reported by Jeff in v7, in patch 6/9.

changes in v7:
 - rebase and remove patch 01/10 which was merged already.

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.
