mac80211: copy configured beacon tx rate to driver (ba6ff70a) · Commits · 戴 / test

The user is allowed to change beacon tx rate (HT/VHT/HE) from hostapd. This information needs to be passed to the driver when the rate control is offloaded to the firmware. The driver capability of allowing beacon rate is already validated in cfg80211, so simply passing the rate information to the driver is enough. Signed-off-by:
