mac80211: notify driver for change in multicast rates
With drivers implementing rate control in driver or firmware rate_control_send_low() may not get called, and thus the driver needs to know about changes in the multicast rate. Add and use a new BSS change flag for this. Signed-off-by: Pradeep Kumar Chitrapu <pradeepc@codeaurora.org> [rewrite commit message] Signed-off-by: Johannes Berg <johannes.berg@intel.com>
