        !            35:  *     Added performance hooks; changed transmit interrupt
        !            36:  *     to only interrupt every N / 2 times, where N is the
        !            37:  *     number of transmit descriptors.  This reduces the
        !            38:  *      number of interrupts taken, and the amount of CPU
        !            39:  *     used by the driver.
        !            40:  * 11-Dec-95   Dieter Siegmund (dieter) at NeXT
        !            41:  *     Re-named 2104x.h, split out 21040 and 21041 personalities.
