From 521a4a23261354885c01bf75b42150629004ed83 Mon Sep 17 00:00:00 2001 From: Arik Nemtsov Date: Mon, 18 Apr 2011 14:15:22 +0300 Subject: [PATCH] wl12xx: AP-mode - disable beacon filtering on start up New AP-mode FWs filter external beacons by default. Disable this filtering on start up so we can properly configure ERP protection.
