Subject: [PATCH 18/32] staging: brcm80211: Fix for WPA GTK install issue in brcmfmac driver
Date: Fri, 13 May 2011 11:59:38 +0200 [thread overview]
Message-ID: <1305280792-9475-18-git-send-email-arend@broadcom.com> (raw)
In-Reply-To: <1305280792-9475-1-git-send-email-arend@broadcom.com>
From: Sukesh Srikakula <sukeshs@broadcom.com>
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.
