libertas_tf
===========

libertas_tf supports the Marvell 88W8388 USB device as found in the
`OLPC XO-1 <http://laptop.org>`__ laptop. Unlike the :doc:`libertas
<libertas>` driver, ``libertas_tf`` uses thin firmware (found `here
<http://dev.laptop.org/pub/firmware/libertas/thinfirm/>`__) with the
``mac80211`` stack.

Enabling libertas_tf
--------------------

To enable ``libertas_tf``, you must first enable ``mac80211``::

   Networking  --->
     Wireless  --->
       <M> Improved wireless configuration API
       <M> Generic IEEE 802.11 Networking Stack (mac80211)

You can then enable ``libertas_tf`` in the kernel configuration::

   Networking  --->
     Wireless  --->
       <M> Marvell 8xxx Libertas WLAN driver support with thin firmware
       <M> Marvell Libertas 8388 USB 802.11b/g cards with thin firmware

firmware
~~~~~~~~

The firmware can be obtained from `firmware tree
<http://git.kernel.org/?p=linux/kernel/git/firmware/linux-firmware.git>`__.

Please also see the `libertastf HOWTO
<http://dev.laptop.org/pub/firmware/libertas/thinfirm/HOW_TO>`__ for
instructions on grabbing the corresponding firmware and loading the
driver. The regular ``libertas`` driver **must** be unloaded and/or
blacklisted in order to use ``libertas_tf``. Additional notes can be
found on the `OLPC WiKi
<http://wiki.laptop.org/go/Libertas_Thinfirmware_HOWTO>`__.
