We currently track TX bitrate info (from NL80211_STA_INFO_TX_BITRATE properties) in our LinkStastics DBus properties, and this gets logged in feedback reports, etc., but we don't do the same for NL80211_STA_INFO_RX_BITRATE, when available. The netlink format is the same, so we should be able to easily reuse our existing code for this.

On a related note: not all drivers actually support this. Particularly, mwifiex seems to log some related info in debugfs, but it doesn't fill it out in the STA info:

mwifiex_dump_station_info(struct mwifiex_private *priv,
                          struct mwifiex_sta_node *node,
                          struct station_info *sinfo)
{
        u32 rate;

        sinfo->filled = BIT_ULL(NL80211_STA_INFO_RX_BYTES) | BIT_ULL(NL80211_STA_INFO_TX_BYTES) |
                        BIT_ULL(NL80211_STA_INFO_RX_PACKETS) | BIT_ULL(NL80211_STA_INFO_TX_PACKETS) |
                        BIT_ULL(NL80211_STA_INFO_TX_BITRATE) |
                        BIT_ULL(NL80211_STA_INFO_SIGNAL) | BIT_ULL(NL80211_STA_INFO_SIGNAL_AVG);
...


I might take a stab at this myself, but if someone else is raring to tackle it, feel free.
