Subject: [PATCH 3.4 09/44] rt2x00: disable TKIP on USB
Date: Mon,  7 Jul 2014 17:06:59 -0700	[thread overview]
Message-ID: <20140707235858.923422763@linuxfoundation.org> (raw)
In-Reply-To: <20140707235858.652771077@linuxfoundation.org>

3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Stanislaw Gruszka <sgruszka@redhat.com>

commit 8edcb0ba0d56f5914eef11eda6db8bfe74eb9ca8 upstream.

On USB we can not get atomically TKIP key. We have to disable support
for TKIP acceleration on USB hardware to avoid bug as showed bellow.
