Follow-up Comment #10, 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

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

>I work on it when I have time. 

Take your time, I don't see this as a pressing issue as long as nobody uses
it (aside from you :)
