Follow-up Comment #46, task #14314 (project lwip):

> If I have a "netif" version of this structure[..] So I'm trying to think of
an API that makes sense at the netif layer and can be easily re-used at the
if_api layer

Just my 2c: isn't it a bit overkill to have a fullblown structure for this at
the netif level at all? How about something like,

1) a netif iterator function:

   struct netif *
   netif_iter(struct netif *prev)
     return ((prev == NULL) ? netif_list : (prev->next));

2) a netif_get_name(netif, buf) function, which could share code with
netif_index_to_name() ?

Any higher layers can construct a list in whatever form they wish using those
