Subject: [PATCH] ath11k: Add htt cmd to enable full monitor mode
A new hw_param full_monitor_mode is added to enable full
monitor support for QCN9074.
HTT_H2T_MSG_TYPE_RX_FULL_MONITOR_MODE cmd is sent to FW
to enable the full monitor mode.
Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.4.0.1-01734-QCAHKSWPL_SILICONZ-1
