[lwip-users] ARP problem

[stephen]

Hi:

 

    I am porting lwIP to a very compact RTOS.

    Is there document for porting guide or port instructions?

    Really appreciate if you can provide any information.

    I will make porting instructions if I can port lwIP to my platform successfully.

 

    One problem is about handling ARP request in etharp.c(lwIP version 0.7)

        line 550 => hdr->shwaddr.addr[i] = ethaddr->addr[i];

        line 586 => update_arp_entry(netif, &(hdr->sipaddr), &(hdr->shwaddr), ARP_INSERT_FLAG);

 

    Looks like "hdr->shwaddr" was changed before ARP table being update.

    Is that correct?

    Thank you!

 

Best Regards,
