[lwip-users] Passing ARP replies to host

[Amena El Homsi]

 Hi,

LwIP processes the ARP requests and replies updated the ARP table, then it calls pbuf_free().

Is there a way to send the ARP reply to the host when the host requested lwIP to send an ARP request?

I was thinking to use raw pcb and define a raw callback function that will inform the host of the result of the ARP request, however raw_input() is not called unless ip4_input is called and since the arp will be processed by etharp_input I will not be able to use raw_pcb.

Thanks,
