Add support for writing a TX descriptor to the NIC in one PCIe
transaction on x86_64 machines.

This absolutely does not belong in a driver.

OK.  My assumption was that 128-bit MMIO on a data path would be so rare
that this would not be generically useful.  (Really long MMIOs are
likely to be done with write-combining, so that the data width of
instructions doesn't matter much.)
