From 5a5b6ed6ce46be128f2a5a9e56f47193c3ac3e32 Mon Sep 17 00:00:00 2001 From: Helmut Schaa Date: Sat, 2 Oct 2010 11:31:33 +0200 Subject: rt2x00: Don't enable broad- and multicast buffering on USB devices Since rt2x00 USB devices have no chance to know when a beacon was sent out in AP mode currently all broad- and multicast traffic is buffered in mac80211 but never sent out at all. Unfortunately we have no chance in sending the traffic out after a DTIM beacon due to hw limitations. Hence, instead of never sending the buffered traffic out better send it out immediately.
