Hehe, that's what happens if developers ignore the RFCs. As far as I remember,
the requirements for internet hosts makes IP reassembly mandatory while
fragmentation is optional...
Of course, it can be disabled in lwIP, too :-)
Ore than that, IP fragmentation and reassembly works with lwIP. I haven't
tested it for a while now, but I see no reason it shouldn't work as we haven't
been changing anything around that code path lately.
