Michael Brown 15a8800a98 [efi] Add a USB host controller driver based on EFI_USB_IO_PROTOCOL Allow iPXE to coexist with other USB device drivers, by attaching to the EFI_USB_IO_PROTOCOL instances provided by the UEFI platform firmware. The EFI_USB_IO_PROTOCOL is an unsurprisingly badly designed abstraction of a USB device. The poor design choices intrinsic in the UEFI specification prevent efficient operation as a network device, with the result that devices operated using the EFI_USB_IO_PROTOCOL operate approximately two orders of magnitude slower than devices operated using our native EHCI or xHCI host controller drivers. Since the performance is so abysmally slow, and since the underlying problems are due to fundamental architectural mistakes in the UEFI specification, support for the EFI_USB_IO_PROTOCOL host controller driver is left as disabled by default. Users are advised to use the native iPXE host controller drivers instead. Signed-off-by: Michael Brown <mcb30@ipxe.org>		9 years ago
