A key property of the bulk function is to make it easy passing on the resulting array of non-malformed packets to the next bulk function, e.g. GRO. A malformed_mask would require an intermediate step of processing before the resulting array can be passed on. For functions like GRO, either the MBUF must contain a valid/malformed indication, or the array provided to them must contain only valid packets. Med venlig hilsen / kind regards - Morten Brørup
