[lwip-users] what's the mean that ARP can be disabled completely?

[embed9527]

 

Hi,

 

 

    In the web http://lwip.scribblewiki.com/LwIP_version_1.3.0_release_notes, about arp, it's a message:

  

    LWIP_ARP option in lwipopts.h. ARP can now be disabled completely.

 

    According to my understanding, arp can be disabled by setting LWIP_ARP = 0 in lwipopts.h just like LWIP_UDP、LWIP_TCP and so on. I have chaged code in the enthernetif.c that it can be work in my target board. if setting LWIP_ARP = 1, LWIP works well, but if setting LWIP_ARP = 0, it is a lot of error.

 

    So, I want to ask what's the mean about the message in above web! how can I do when I want to set LWIP_ARP = 0?

 

Thanks!
