iwlwifi: mvm: fix MCAST in AP mode
In multicast, there is no retries nor RTS since there is no specific recipient that can ACK or send CTS. This means that we must not use the rate scale table for multicast frames. This true for any frame that doesn't have a valid ieee80211_sta pointer. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
