FWIW In the big scheme of things (especially when you strip it down a
little bit at the CONFIG option level or perhaps use the 2.4 version)
the Linux stack is not actually that heavy in memory. In particular
many other stacks tend to use pre-allocated packet pools which can
easily use a lot more memory than the code delta even of a larger
stack. The Linux stack at least in most drivers doesn't do that and
only allocates memory on demand. There are unfortunately now a few
highend drivers who start using preallocated pools too, but these can
be still easily avoided.
