wifi: ath12k: debugfs: radar simulation support
Create dfs_simulate_radar debugfs in ath12k debugfs directory.
Usage:
echo 1 > /sys/kernel/debug/ath12k/pci-0000:06:00.0/mac0/dfs_simulate_radar
This debugfs helps user to simulate RADAR interference in run time.
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
