If anyone has any objections, please let me know. ------------------ From: Emmanuel Grumbach 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.
