Re: [lwip-users] STM32F107 LwIP Porting v1.3.2 to v1.4.1

[Sergio R. Caprile]

lwipopts.h is platform independent, and a subset of src/include/lwip/opt.h
you basically do not modify src/include/lwip/opt.h but change what you
need by putting it in lwipopts.h

The CHECKSUM_BY_HARDWARE defines depend on you and your platform, if it
has a checksum engine and you want to offload checksum calculation to it.

I guess you mean you've had to "add" those files to "the project", that
is, mark them to be compiled in.

This seems to be correct when first upgrading, as per the file "UPGRADING"

That is not an lwIP file, that file belongs to your vendor.
