[lwip-devel] [patch #6760] Ping calculates incorrect checksum

[Simon Goldschmidt]

Follow-up Comment #3, patch #6760 (project lwip):

> I'm not sure the patch, as checked in, works.

Not sure or do you know it doesn't work?

- ICMP header is 8 bytes
- with PING_DATA_SIZE=64, 64 bytes of additional data are currently filled
in
- checksum length is 72 (header + add. data)
- wireshark shows checksum is correct

Unfortunately, I do not get an answer when pinging, but that may well be a
problem with my windows or VM - as I said, wireshark does NOT complain about
the ping packets.
