libertas_tf supports the Marvell 88W8388 USB device as found in the OLPC XO-1 laptop. Unlike the libertas driver, libertas_tf uses thin firmware (found here) 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


Please see the libertastf HOWTO 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.
