Is it limited on both tx and rx or only one?
Both, as I understand it. I think maybe we could use the max-tx-rate and max-rx-rate fields in the vht mcs info field to give user-space a clue. Thanks, Ben

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?
