Hi,

>> Ralink has provided a new driver for the rt2860 hardware,

>> it hooks into mac80211.
>> It doesn't hook into rt2x00lib yet, and neither does it support everything
>> mac80211 could do, but it can be used as base for further developing
>> the rt2800pci drivers by filling the last remaining gaps.

>> The driver can be found here:

>> Mark, Matthias and Felix you offered/provided help with the rt2800 developers

I fixed this issue 2 days ago, you might want to update your
rt2x00.git checkout. :)
