1. If strong DC or low frequency sing wave like signal (suspect it is generated by ad9361 during some self-calibration like operation), put the receiver into reset
2. If the signal/header is valid, but the packet length is abnormal (signal_len<14 || signal_len>max_signal_len_th), reset the receiver
> 1. Leave the module always enabled, so the slv_reg1 is free
> 2. Use the slv_reg1 to force ht smoothing
> 3. By default, the smoothing option of the receiver is still controlled by the received ht packet
