This patch series updates LWIP to 1.4.1. It seems to work well for us,
but we have not run all the tests or touched anything like all the
different config possibilities. Please test and give feedback.
This patch series is generated from git (whatever happened to moving
away from cvs?), hopefully people won't have a problem with that. If you
want build bisectability then the first 5 patches should actually be
merged into one. They are presented separately here so people can see
our working when updating lwip. We have not added cdl options for
absolutely every new option in lwip, just the ones we felt were needed.
Summary of the patches:
* Patches 1-5 update the lwip version
* Patch 6 improves the cdl menu slightly
* Patches 7 & 8 tidy up the code
* Patch 9 fixes a bug in lwip (It was present in earlier version of
lwip as well)
