[lwip-devel] [task #1551] Make ARP more independent of interface hardware type

[Nicolas Pinault]

Follow-up Comment #11, task #1551 (project lwip):

>>It seems to me that we can reuse etharp.c with some modifications.

>As far as I can see it, what can be reused is
>- finding an arp entry
>- the calling structure (netif->input calls arp_output which calls
netif->linkoutput)
>
And packet buffering (when sending to an unresolved IP address)

>But since the arp table (and maybe some functions as entrypoints), I think
it would be best to create another ARP module and link it instead of etharp.
>
>>A specific arp.c module for each interface where entry points are set in
the netif structure.

>If used simultaneously, I think this would be the best solution as I don't
see much code can be reused. (If we make it clear etharp.c is only for
ethernet, we can also have some speedup by defining hwaddr_len to always be
6.)

What about DHCP in this case ?

it (aside from you :)

Unfortunately, you are right.
