Subject: iwlwifi: mvm: tell firmware to let multicast frames in
From: Emmanuel Grumbach <emmanuel.grumbach@xxxxxxxxx>
commit 51b6b9e029e81c857f9d8d17060f499cd25febdb upstream.
Without this command, the firmware will filter out all the
multicast frames. Let them all in as for now. Later we will
want to optimize this to save power.
