[lwip-devel] ARP Table limited to 127 (s8_t)?

[Fabian Koch]

Hey all,

I was wondering if there is a reason for ARP_TABLE_SIZE to be limited to s8_t 
instead of u8_t?
We would need an ARP_TABLE_SIZE of at least 192 and would have to modify the 
stack for that. (LWIP 1.4.1)

I can see some tricks where the s8_t is used as a return value in some 
functions and thus indicates an error when negative. 
But is there any showstopper reason to not pump it up to an u8_t?

cheers,
Fabian
