The clone is used immediately to set cloned->len, so\nan skb_clone() failure results in a NULL pointer dereference.\n\nCheck the clone before using it. If previous fragments were already\nqueued, preserve the driver's existing partial-write behavior by\nreturning the number of bytes submitted so far.",
