Hello! I am porting some network applications from Linux to lwIP stack. So far the progress has been good, but while some stress tests I often see checksum errors being reported by the network sniffer. The ethernet chip does not have any checksum generation support, and so we rely on the software algorithms available inside lwIP library. Have you guys seen such a problem before? Endianness on the system is little-endian, but I believe the algorithm already takes care of that.
Also I don't quite follow the need for check on len being odd and swapping the acc inside inet_chksum_pseudo (and similar) functions. I think that's already taken care off in lwip_standard_chksum functions. Any thoughts on this? Regards, Sourath
