[PATCH rtw-next 12/15] wifi: rtw89: 8852a: fix RSSI report when average beacon RSSI is not ready

[Ping-Ke Shih <pkshih@realtek.com>]

From: Chih-Kang Chang <gary.chang@realtek.com>

8852A uses the average beacon RSSI to smooth the RSSI. However, before
the average beacon RSSI is available, the RSSI should use the PPDU
status RSSI of the received packet to avoid reporting the RSSI as -110 dBm.
