Subject: [PATCH RFC] rt2500usb: disable broken HW encryption by default
Date: Mon, 22 Mar 2010 16:01:35 +0100	[thread overview]
Message-ID: <201003221601.36559.linux@rainbow-software.org> (raw)

Since HW encryption was added to rt2500usb in 2.6.29, the driver does not
work. It has been discussed before but never solved:
http://rt2x00.serialmonkey.com/phpBB/viewtopic.php?f=4&t=4834
https://bugzilla.redhat.com/show_bug.cgi?id=484888

The problem is caused by this patch:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=dddfb478b26e29a2b47f655ec219e743b8111015

Disable HW encryption by default to fix it.
