I will work with the FreeBSD driver, the Linux driver, and the UEFI
driver (for this one, because I fear the AMD IOMMU could come in the
picture, and the card once "working", what was seen with usbxhci may
reproduce itself with the ethernet card; since the UEFI driver works---probably
in a suboptimal mode or speed---this would give a hint about what to do to have
it at least basically working).
