Yes. And this's more like a 'limit', and it actually re-initializes
firmware rate control for each peer to add a boundry on top of rate
table. When you specify something like 'iw dev wlan0 set bitrates
vht-mcs-5 1:9', which means nss=1 mcs0-9 actually. If you would like
stick to a fixed rate then there's a knob in mt7915 debugfs.
As for other the mgmt, mcast, bcast should sill remain in low rate.
