[lwip-devel] About ARP and netif state (up / down)

[address@hidden]

Hi all,

Just a quick question:

May ARP answer an ARP packet asking for the local address if the netif 
state is down? It currently only checks whether netif->ip_addr == 0 
(which is the case when starting DHCP).
But I think it should be quiet if 'downed', shouldn't it? And maybe it 
shouldn't even update its cache while it is down?

Of course, normally you wouldn't expect to even get packets when down 
but it has to when DHCP is started for example...
