Re: [lwip-users] how to handle ARP request that's not for me

[dogeye]

Thank you, Kiran, for the explanation.  Yes, i got the idea, so it's
basically a implementation choice, like windows xp doesn't update ARP
table if the request is not for it. In this way, we can avoid the
trouble that the ARP table will filled up quickly in a large network,
and we need search entire table every time. There are cons and pros
for both ways. Am I right?
