In the driver, if CLUB_LL_STATS_AND_GET_STATION feature is enabled, host requests Link Layer stats and station stats from firmware periodically using a single WMI command. Host then sends LL_STATS to userspace and caches station stats in the adapter. Whenever userspace queries station stats, based on the sta_stats_cached_timestamp, host returns cached stats from adapter instead of sending a new WMI request. The current issue, as part of station stats firmware also sends connection_tx_power stats, which aren't cached into the adapter. So, whenever userspace queries get_tx_power via nl commands, host sends a WMI request to firmware for tx_power leading to platform wakeups and power impacts. To resolve this issue, cache the tx_power sent by firmware into the adapter during station stats and return the cached value to the user space.
