Subject: iwlwifi: mvm: fix MCAST in AP mode
From: Emmanuel Grumbach <emmanuel.grumbach@xxxxxxxxx>
commit 9116a3683902583a302ac5dcb283416d504d9bb4 upstream.
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.
