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.
