s390/qeth: prepare for copy-free TSO transmission
Add all the necessary TSO plumbing to the copy-less transmit path.
This includes calculating the right length of required protocol headers,
and always building a separate buffer element for the TSO headers.
A follow-up patch will then switch TSO traffic over to this path.
