Hello, I just saw a post about VIA controllers triggering IOMMU errors.
Just want to also point out that the ax88179 will also trigger PTE read errors when using the vendor's driver. I'm nowhere near an expert but I remember seeing that 'TD fragment' is supported now or some such, which I take to mean that sg/tso should be supported with usbnet ? I'm unclear on whether it can ever work with intel hosts because of an errata ? Anyway for anyone that wants to see the error you can grab the vendor driver: http://www.asix.com.tw/FrootAttach/driver/AX88179_178A_LINUX_DRIVER_v1.18.0_SOURCE.tar.bz2 This driver was working recently-ish perhaps around the same time the VIA controllers starting having iommu issues.
