ath10k: fw_stats not reporting peer_stats with 10.2

I have a device equipped with a ath10k driven wifi card, specifically:

qca988x hw2.0 (0x4100016c, 0x043202ff) fw 10.2-00082-4-2 api 3 htt 2.1
wmi cal file

(line grabbed from dmesg at boot time)

On my device I have configured 2 AP vifs and for each of them I would
like to read the last TX rate of the associated stations.

As I've read on this is not possible through the
standard nl/cfg80211 interface and therefore I have been trying to read
/sys/kernel/debug/ieee80211/phy1/ath10k/fw_stats  , but this file always
reports "ath10k PEER stats (0)" (no peers..).

I tried printing some debug messages here and there and the only useful
information I got is that in "ath10k_wmi_10x_pull_fw_stats()" the value
of "ev->num_peer_stats" is always 0.

Is this yet another fw limitation?

I also realized that upon station connection ath10k receives the
WMI_10_2_PEER_RATECODE_LIST_EVENTID event but it is not handled as no
handler is implemented. Might it be related with my problem ?

Thanks a lot for any information you would be able to provide :)
