[lwip-users] etharp_output() slow down sending speed ?!

[cyhong]

I have following the samples of 0.7.x version, and I write the  code to the
lwip 1.1.0 version!!
Indeed, the following codes　(CODE I & II) do work ,  but "CODE I" will
send double packets(all of unicast-packets).
I know the problem!!
But donot anyone found that ....
　　　　 if I use "CODE II" to communicate  to　a linux user mode socket
program .
　　　　 the sending speed will slow down, but  the "CODE I" will send
much fast!!
　　　 it is so strange!!

ps. BTW, I donot call the etharp_tmr() rightnow, I think　  it is fine to
communicate with　only one　machines!!


-------------------------------------------
CODE I:

err_t mintapif_output(struct netif *netif, struct pbuf  *p,　 struct
ip_addr *ipaddr)
{
　 etharp_output(netif, ipaddr,  p);　　 // original p=etharp_output();
　 if (p != NULL) {
　　　  return low_level_output(netif, p);
　 }
　 return  ERR_OK;
}

--------------------------------------------
CODE II:
err_t mintapif_output(struct netif *netif, struct pbuf  *p,　 struct
ip_addr *ipaddr)
{
　　　　　 return  etharp_output(netif, ipaddr, p);
}
