Thank you, this is extremely helpful for us. Do you know any device that supports more than 2 spatial streams? (Is mt76 capable of supporting more spacial streams at the moment?)

I was actually wondering what hardware was used to test the code. It seems Lorenzo Bianconi used an D-Link DIR-860L rev B1 [1] Yes, I used it for a while; at the moment to work on mt76 code I am using Buffalo wsr1166 Regards, Lorenzo Kind regards, Sven [1] https://patchwork.kernel.org/patch/8393091/

Following files use IEEE80211_TX_RC_VHT_MCS in drivers/net/wireless: * intel/iwlwifi/mvm/tx.c * mac80211_hwsim.c * mediatek/mt76/mt76x2_mac.c * mediatek/mt76/mt76x2_tx.c * realtek/rtlwifi/base.c * realtek/rtlwifi/rc.c Following files from the candidates are providing their own rate_control_ops: * realtek/rtlwifi/ * intel/iwlwifi/mvm/rs.c * intel/iwlwifi/dvm/rs.c So I would currently bet on hwsim (only useful when you only want to have some simulations) or mt76. Afaik mt76 was also the one which was used to test the VHT rate injection code for monitor interfaces and is therefore quite flexible.
