Appendix B "EHCI 64-Bit Data Structures" of the "Enhanced Host Controller Interface Specification for Universal Serial Bus" (Rev. 1.0, March 12, 2002) defines additional fields which were missing in U-Boot's struct qTD; as these are also present in recent versions of struct ehci_qtd in the Linux kernel, we add them here, too.
This fixes some nasty memory corruption problems.

this patch goes back to an old posting by Dan Lykowski.
Unfortunately Dan never submitted a patch, so this went unfixed until now, when the bug bit Stefano...
Best regards,
