From e37b674156b9d5cd87025f0b4719d60e4ac6060c Mon Sep 17 00:00:00 2001 From: Christian Lamparter Date: Sun, 2 Sep 2012 14:25:50 +0200 Subject: [PATCH] carl9170: connect to 11w protected networks Previously, it was not possible to connect to networks which requires 11w to be supported by the stations. While the documentation hints that there's some hardware support for offloading MFP "decryption", this simple implementation relies on the mac80211 stack to do the actual crypto operations.
