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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
