arpinit.c

关于ARP协议方面的。比较难的。。不过是源码

/* arpinit.c - arpinit */

#include <conf.h>
#include <kernel.h>
#include <proc.h>
#include <network.h>

/*------------------------------------------------------------------------
 *  arpinit  -  initialize data structures for ARP processing

void arpinit()
{
	int	i;

	rarpsem = screate(1);
	rarppid = BADPID;

	for (i=0; i<ARP_TSIZE; ++i)
		arptable[i].ae_state = AS_FREE;
}

int	rarpsem;
int	rarppid;

struct	arpentry	arptable[ARP_TSIZE];
