안녕하세요..
이곳 저곳에서 자료 찾아, 공부해서 작성한 패킷 캡처 프로그램입니다.
2.4에서는 돌아갔는데... 2.6에서는 컴파일 에러가 발생하네요..

};

printk(KERN_ALERT "headroom size : %d\n", (skb->data - skb->head));
return skb->len;
}
int init_module(void)
{
printk(KERN_ALERT "Module start!!\n");
dev_add_pack(&test_protocol);
return 0;
}
void cleanup_module(void)
{
dev_remove_pack(&test_protocol);
}

에러를 발생하는 파일(irq.h)를 열어보았더니, irq_vectors.h라는 파일을
include하는데.. 이 파일의 정체를 알수가 없네요..
도움 부탁드립니다..
Forums:
NR_IRQS나 NR_IRQ_VECTORS 는 irq_vector
NR_IRQS나 NR_IRQ_VECTORS 는
irq_vectors_limits.h 에 선언되어 있군요.
혹시 arch에 따른 header file의 link가 아직 안 만들어져 있는것 아닌가요?
그나저나 저 루틴을 이용한 패킷 캡처 모듈을
다른곳 참조하지 않고 그냥 소스 보다가 문득 생각났는데요 ...
그땐 그게 어찌나 기쁘던지...
내가 발견 했어!하고 생각했었는데 일반적으로 사용되는군요 :)
