[PATCH 5.6 138/167] staging: vt6656: Dont set RCR_MULTICAST or RCR_BROADCAST by default.

[Greg Kroah-Hartman]

From: Malcolm Priestley <tvbox...@gmail.com>

commit 0f8240bfc070033a4823b19883efd3d38c7735cc upstream.

mac80211/users control whether multicast is on or off don't enable it by 
default.

Fixes an issue when multicast/broadcast is always on allowing other beacons 
through
in power save.

Fixes: db8f37fa3355 ("staging: vt6656: mac80211 conversion: main_usb add 
functions...")
