Subject: [PATCH] Fix SPARC64 unaligned access in zd_mac_rx
Content-Type: text/plain; charset=ISO-8859-1; format=flowed
Sender: linux-wireless-owner@vger.kernel.org
List-ID: <linux-wireless.vger.kernel.org>

I'm running zd1211rw on SPARC64 and was getting a lot of "unaligned 
access" messages in dmesg.  I tracked the problem down to this line, and 
changing the cast to a memcpy fixes the issue.

Please CC me with any comments as I am not subscribed to the list.
