Subject: [PATCH 143/151] ath11k: report rssi of each chain to mac80211 for
QCA6390/WCN6855
Command "iw wls1 station dump" does not show each chain's rssi currently.
If the rssi of each chain from mon status which parsed in function
ath11k_hal_rx_parse_mon_status_tlv() is invalid, then ath11k send
wmi cmd WMI_REQUEST_STATS_CMDID with flag WMI_REQUEST_RSSI_PER_CHAIN_STAT
to firmware, and parse the rssi of chain in wmi WMI_UPDATE_STATS_EVENTID,
then report them to mac80211.
WMI_REQUEST_STATS_CMDID is only sent when CONFIG_ATH11K_DEBUGFS is set,
it is only called by ath11k_mac_op_sta_statistics(). It does not effect
performance and power consumption. Because after STATION connected to
AP, it is only called every 6 seconds by NetworkManager in below stack.
