I've got my Mac IIci (68030/25) running as a NAT box at 115,200 bps with an
ISDN TA. The machine is essentially unresponsive during transfer bursts,
but it gives ~7,100 bytes/sec without dropping a single packet.

Actually, I was pretty surprised to hear the sparc port cuts off at 38k4.
Is this an interrupt priority issue?
