I think something is wrong still. I tested this with 999.999.0.636 on
x86 32 bit laptop in AP mode, connected STA 00:24:d7:9b:0b:7c to it and
still MAC address is wrong:

              PHY errors drops          0
   MPDU errors (FCS, MIC, ENC)          0

             ath10k PEER stats
             =================

              Peer MAC address 9b:d7:24:00:00:00
                     Peer RSSI 36
                  Peer TX rate 0

Without your patch it's also wrong:

             ath10k PEER stats
             =================

              Peer MAC address 00:00:00:00:02:00
                     Peer RSSI 3
                  Peer TX rate 0

              Peer MAC address 00:00:00:00:00:24
                     Peer RSSI 31755
                  Peer TX rate 0

Any ideas what's happening here?

Should we show "self peer" separately? Does it provide any useful
information?
