Всяко бывает с экзотерическими архитектурами. Особенно в экзотических режимах.

FUTURE
* TODO: The lwIP source code makes some invalid assumptions on processor
word-length, storage sizes and alignment. See the mailing lists for
problems with exoteric (/DSP) architectures showing these problems.
We still have to fix some of these issues neatly.
* TODO: the ARP layer is not protected against concurrent access. If
you run from a multitasking OS, serialize access to ARP (called from
your network device driver and from a timeout thread.)
* TODO: the PPP code is broken in a few ways. There are namespace
collisions on BSD systems and many assumptions on word-length
(sizeof(int)). In ppp.c an assumption is made on the availability of
a thread subsystem. Either PPP needs to be moved to contrib/ports/???
or rearranged to be more generic.
* TODO: review the the sequential netconn and socket API (lwip/src/api)
for bugs and performance issues. Frequent system calls (e.g. sys_mbox_fetch)
slooow things down considerably.
