FWIW, the plan looks fine to me. Just adding a couple of hints to simplify the implementation. Sarah Sharp [off-list ref] writes:quoted
Let's do this fix the right way, instead of wall papering over the issue. Here's what we should do: 1. Disable scatter-gather for the ax88179_178a driver when it's under an xHCI host.No need to make this conditional. SG is only enabled in the ax88179_178a driver if udev->bus->no_sg_constraint is true, so it applies only to xHCI hosts in the first place.
Leave the usbnet code alone and unset udev->bus->no_sg_constraint. David
