A 6GHz AP can decide to transmit Beacon, Broadcast probe response
and FILS discovery frames in a non-HT duplicate PPDU when
operating in non 20MHz Bandwidth to enhance its discoverability.
(IEEE Std 802.11ax‐2021-26.17.2.2)
Send WMI_VDEV_PARAM_6GHZ_PARAMS with enable/disable option to FW
based on he_6g_nonht_dup_beacon_set.
Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.5.0.1-01100-QCAHKSWPL_SILICONZ-1
