To fix a bug, a flag to announce the capabitlity to support the zero-copy forwarding on the consumer side will be added on the SE descriptor. So the old flag SE_FL_MAY_FASTFWD is renamed to indicate it concerns the producer side. It is now SE_FL_MAY_FASTFWD_PROD. And to prepare addition of the new flag, the bitfield is a bit reordered.
