    rt2x00: Align RX descriptor to 4 bytes · f855c10b
    Ivo van Doorn authored
    Some architectures give problems when reading
    RX frame descriptor words when the descriptor
    is not aligned on a 4 byte boundrary.
    Due to optimalizations for the ieee80211 payload
    4 byte alignment, it is no longer guarenteed
    that the descriptor is placed on the 4 byte
    boundrary (In fact, for rt73usb it is absolutely
    never aligned to 4 bytes, for rt2500usb it depends
    on the length of the payload).
    This will copy the descriptor to a 4 byte aligned
    location before it is read for the first time.
    This will also move the payload data alignment
    in rt2x00usb (instead of inside the driver) where
    it has always belonged.
