 ** RCResetLANCard()
 **
 ** Reset LAN card operation.  Causes a software reset of the ethernet
 ** controller and restarts the command and receive units. Depending on 
 ** the ResourceFlags given, the buffers are either returned to the
 ** host with reply status of I2O_REPLY_STATUS_ABORT_NO_DATA_TRANSFER and
 ** detailed status of I2O_LAN_DSC_CANCELED (new receive buffers must be
 ** posted after issuing this) OR the buffers are kept and reused by
 ** the ethernet controller. If CallbackFunction is not NULL, the function
 ** will be called when the reset is complete.  If the CallbackFunction is
 ** NULL,a 1 will be put into the ReturnAddr after waiting for the reset 
 ** to complete (please disable I2O interrupts during this method).
 ** Any outstanding transmit or receive buffers that are complete will be
 ** returned via the normal reply messages before the requested resource
 ** buffers are returned.
 ** A call to RCPostRecvBuffers() is needed to return the ethernet to full
 ** operation if the receive buffers were returned during LANReset.
 ** Note: The IOP status is not affected by a LAN reset.
