So, it appears that the ath10k QCA9984 4x4 160Mhz chip can do 4x4 MIMO at VHT80, but it can do only 2x2 MIMO at VHT160/80+80. When configuring a peer, we need to tell the firmware the number of spatial streams of the peer at VHT160 and at VHT80 and lower. They are not the same value. I cannot think of any standard way to get this information based on VHT capabilities and such. Currently, one could just assume VHT160 NSS is 1/2 of the VHT80 NSS, but that is unlikely to be true for all vendors. Any ideas?
