2.18.0
Add runtime configuration for bitrate mask. This update firmware rate
control to add a boundary on top of table to limit the rate selection
for each peer, so when user set bitrates vht-mcs-5 1:9, which actually
means nss = 1 mcs = 0~9. This only applies to data frames as for other
mgmt, mcast, bcast still use legacy rates as it is.
Note that driver does not support GI configuration.
Example:
iw dev wlan0 set bitrates vht-mcs-5 1:9 he-mcs-5 2:7
iw dev wlan0 set bitrates legacy-5 6 he-mcs-5 2:0-11
