[PATCH v3] wifi: ath11k: support DBS and DFS compatibility

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Now some chips which support 'support_dual_stations' will enable DBS,
but will disable DFS. Restructure the ath11k_mac_setup_iface_combinations
function to support DBS and DFS compatibility.

About 'support_dual_station' feature can refer:
https://msgid.link/20230714023801.2621802-2-quic_cjhuang@xxxxxxxxxxx

Add a ieee80211_iface_combination to support DBS and DFS compatibility,
one combination can support DFS(same with non dual sta), another
combination can support DBS. When running different scenarios that will
use different ieee80211_iface_combination due to mac80211 will go through
all of possible interface combinations.

In addition, maximum number of interfaces of these types should be total
allowed in this group.

The chips affected are:

 QCA6390 hw2.0
 WCN6855 hw2.0
 WCN6855 hw2.1

Other chips are not affected.

Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.1.0.1-00410-QCAHKSWPL_SILICONZ-2
Tested-on: IPQ6018 hw1.0 AHB WLAN.HK.2.1.0.1-01161-QCAHKSWPL_SILICONZ-1
Tested-on: WCN6855 hw2.1 PCI WLAN.HSP.1.1-04402-QCAHSPSWPL_V1_V2_SILICONZ_IOE-1.
