ne2000.c

我自己写的一个tcp/ip的代码

#include "eth_typedef.h"
#include "mbuf.h"
#include "string.h"
#include "ip.h"

NETSET my;

void ne2000_init()
{
}

void ne2000_send()
{
	unsigned int len;
	unsigned char sendbuf[TCP_MAX_WINDOWS_SIZE];
	len = mbuf_r((unsigned char *)&sendbuf[0]);
	if(len == 0)
	{
		return;
	}
}

unsigned char teststring[500] = {'0'};
unsigned char eth_rece_buf[TCP_MAX_WINDOWS_SIZE + 80];
unsigned int ne2000_rece_data()
{
	unsigned int ilen;
	ilen = 0;
	memcpy((unsigned char *)&eth_rece_buf[0], (unsigned char *)&teststring[0], 500);
	ilen = 500;
	return ilen;
}

void ne2000_rece()
{
	ETH_HEADER * eth;
	if(ne2000_rece_data() == 0)
	{
		return;
	}
	eth = (ETH_HEADER *)&eth_rece_buf[0];
	switch(eth->frame_type)
	{
	case ARP_PACKET:
		//arp_handle();
		break;
	case IP_PACKET:
		ip_handle((unsigned char *)eth);
		break;
	}
}

void ne2000_run()
{
	ne2000_rece();
	ne2000_send();
	ne2000_send();
	ne2000_send();
}
