From 960334a7d33ecd54ba5337275dc4ea701d1dbf5e Mon Sep 17 00:00:00 2001 From: Christian Lamparter Date: Sat, 8 Sep 2012 01:48:19 +0200 Subject: [PATCH] p54: connect to 11w protected networks Previously, it was not possible to connect to networks which requires 11w to be supported by the stations. Note: As all current (and old) firmwares corrupt incoming, protected management frames, the decryption offloading needs to be disabled. This will be done automatically if needed.
