user-mode TCP/IP stack based on linux tap device

tapip's Issues

using NULL pointer in `tcp_send_ack`

tcp_text.c:129: tcp_send_ack(tsk, NULL); may cause errors if argment seg is NULL,

no tcp retransmit support？

Wrong perrx statement

This line ,
perrx("ioctl SIOCGIFHWADDR");
should be ,
perrx("ioctl SIOCGIFMTU");

void getmtu_tap(unsigned char *name, int *mtu){ struct ifreq ifr = {};

`strcpy(ifr.ifr_name, (char *)name);
/* get net order hardware address */
if (ioctl(skfd, SIOCGIFMTU, (void *)&ifr) < 0) {
	close(skfd);
	perrx("ioctl SIOCGIFHWADDR");
}
*mtu = ifr.ifr_mtu;
dbg("mtu: %d", ifr.ifr_mtu);

}`
