[lwip-devel] [task #14314] Implement interface name/index APIs

[David van Moolenbroek]

Follow-up Comment #17, task #14314 (project lwip):

Yes :) Specifically I have an array of netif-containing structures, so I use
an O(n) lookup to find a free one (a free list would make that O(1), even).
Then I can set netif->num based on the array index. As such, in my use case,
the netif_num value is completely unused, so it's also not a problem if it
overflows or whatever, as long as I can set netif->num myself.
