From 22d5d59b8c4bac63b1466dce5bee5dc48e8ee447 Mon Sep 17 00:00:00 2001 From: Sukesh Srikakula Date: Fri, 13 May 2011 11:59:38 +0200 Subject: [PATCH] staging: brcm80211: Fix for WPA GTK install issue in brcmfmac driver Last 16 bytes of the key sent by cfg80211 needs to be swapped before installing it to FW for TKIP encryption. This is not done for group key in current code, which is corrected with this fix.
