Consistent with another report that says that ethernet worked provided
that TSO was disabled (ie no sg tx).
(Without the patch to delay he ownership change on link trbs it didn't
work at all.)
A guess...
In queue_bulk_sg_tx() try calling xhci_v1_0_td_remainder() instead
of xhci_td_remainder().
You can try that on top of either of my other patches.
