[lwip-devel] [bug #54506] LWIP_CHECKSUM_ON_COPY causes wrong checksum (0xFFFF)

[Simon Goldschmidt]

Follow-up Comment #1, bug #54506 (project lwip):

I think the correct version of the fix is to invert back 'acc' (as it is
returned inverted by ip_chksum_pseudo_partial()), then do the calculation and
fold and then inverting it again. As that is the same what's already done, it
should be portable.

See attached patch.
