We have ported uC/IP to eCos which is a smallish TCP/IP stack developed
in ANSI C for embedded systems.
It supports e.g. PPP and we have been using it successfully for more
than a year.
During this time fixed some really serious bugs and now it seems to work
very well. We have been using PPP/TCP/IP over a GPRS modem (it works
fine in the contries we have tried, e.g. Sweden, UK, even Brazil!).
If anyone are interested, we would like to contribute the bugfixes and
eCos port. The licence is BSD since the code is based on the BSD stack.
The project is hosted at "http://sourceforge.net/projects/ucip/"; but
unfortunately nothing seems to have happend for the last few years.
Maybe its better to contribute the code to the eCos repository? Maybe
the existing BSD-based eCos stacks and the Siemens stack make this stack
superfluous?
Here follows a simple example of a memory benchmark for the files in
uC/IP for different sections (using arm-elf-gcc 3.4.0) to compare with
other BSD-based stacks perhaps.
(The stack does not allocate any dynamic memory, it handles all memory
allocation internally with static memory, which is a feature.)

(I'm sure the mem size could be reduced. This is _all_ code [not
linked], and also the amount of internal data buffers could be reduced.)
