From 84b60c144cd32db5ca5185405e9b3f84cac9df9a Mon Sep 17 00:00:00 2001 From: Grazvydas Ignotas Date: Sat, 16 Jun 2012 22:31:50 +0300 Subject: wl1251: send filters to firmware as they are set Firmware supports changing filters using ACX_RX_CFG command, so use it in .configure_filter callback. Firmware also supports probe request filtering, so add it too along the way. This will also re-enable BSSID filter which is now removed by join command while associating.
