Probably pretty obvious, but adding a flag "if bad hwsum, then try softsum" probably wouldn't be too hard. Of course it depends on how often it mangles the checksum, if it's quite often it's probably just a better idea to do it in software to lift some load from the card if doing the hw checksum actually taxes the card.
