29: *
30: * HISTORY
31: *
32: * 26-Apr-95 Rakesh Dubey (rdubey) at NeXT
33: * Created.
34: * 11-Oct-95 Dieter Siegmund (dieter) at NeXT
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.
42: * 07-Feb-96 Dieter Siegmund (dieter) at NeXT
43: * Fixed multicast.
