[lwip-devel] rfc: changing netif_add prototype

[Jani Monoses]

Currently netif_add uses mem_malloc to allocate a netif struct. I
propose changing it to accept a pointer to an already existing struct
netif and fill that, so it does not depend on mem.c. This type of
operation is only requested a few times and most of the times it's fixed
at system build time.
(this is the first and by far the easiest step towards malloc-free lwip,
the other users being pbuf.c and dhcp.c)
