注册中断处理程序，指定中断触发方式，修改net_open函数： #if 0
writereg(dev, PP_BusCTL, ENABLE_IRQ | MEMORY_ON); #endif
write_irq(dev, lp->chip_type, dev->irq); #if defined(CONFIG_ARCH_S3C2410)
ret = request_irq(dev->irq, &net_interrupt, IRQF_TRIGGER_RISING, dev->name,
dev); #else
ret = request_irq(dev->irq, &net_interrupt, 0, dev->name, dev); #endif
在drivers/net/cs89x0.c中适当的位置加上CONFIG_ARCH_S3C2410宏编译开关,
