    DESCRIPTION

         The ral driver supports PCI/CardBus wireless adapters based on the Ralink
         Technology RT2500, RT2501, and RT2600 chipsets.
    
         The RT2500 chipset is the first generation of 802.11b/g adapters from
         Ralink.  It consists of two integrated chips, a RT2560 MAC/BBP and a
         RT2525 radio transceiver.
    
         The RT2501 chipset is the second generation of 802.11b/g adapters from
         Ralink.  It consists of two integrated chips, a RT2561 MAC/BBP and a
         RT2527 radio transceiver.  This chipset provides support for the IEEE
         802.11e standard with multiple hardware transmission queues and allows
         scatter/gather for efficient DMA operations.
    
         The RT2600 chipset consists of two integrated chips, a RT2661 MAC/BBP and
         a RT2529 radio transceiver.  This chipset uses the MIMO (multiple-input
         multiple-output) technology with multiple antennas to extend the operat-
         ing range of the adapter and to achieve higher throughput.  MIMO is the
         basis of the forthcoming IEEE 802.11n standard.
    
         The transmit speed is user-selectable or can be adapted automatically by
         the driver depending on the received signal strength and on the number of
         hardware transmission retries.
    
         ral supports station, adhoc, hostap, mesh, wds, and monitor mode opera-
         tion.  Only one hostap or mesh virtual interface may be configured at a
         time.  Any number of wds virtual interfaces may be configured together
         with a hostap interface.  Multiple station interfaces may be operated
         together with a hostap interface to construct a wireless repeater device.
         For more information on configuring this device, see ifconfig(8).

    DIAGNOSTICS

         ral%d: could not load 8051 microcode  An error occurred while attempting
         to upload the microcode to the onboard 8051 microcontroller unit.
    
         ral%d: timeout waiting for MCU to initialize  The onboard 8051 microcon-
         troller unit failed to initialize in time.
    
         ral%d: device timeout  A frame dispatched to the hardware for transmis-
         sion did not complete in time.  The driver will reset the hardware.  This
         should not happen.
