In the Linux kernel, the following vulnerability has been resolved: net: ethernet: cortina: Use TOE/TSO on all TCP It is desireable to push the hardware accelerator to also process non-segmented TCP frames: we pass the skb->len to the "TOE/TSO" offloader and it will handle them. Without this quirk the driver becomes unstable and lock up and and crash. I do not know exactly why, but it is probably due to the TOE (TCP offload engine) feature that is coupled with the segmentation feature - it is not possible to turn one part off and not the other, either both TOE and TSO are active, or neither of
