4 Subject: [PATCH] wifi: ath11k: Add support to configure FTM responder role
5
6 Fine Timing Measurement(FTM) support is used to measure round trip
7 time between two nodes.
8
9 Enable FTM responder feature using hw_params on supported device.
10 Since FTM functionality is offloaded to firmware, adding the
11 interface allows user space to enable or disable FTM responder.
12 Also add support for advertising the same in extended capabilities.
13
14 QCA6390, WCN6855 and WCN6750 do not support this feature.
15
16 Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.7.0.1-01744-QCAHKSWPL_SILICONZ-1
17 Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.7.0.1-01744-QCAHKSWPL_SILICONZ-1
