in SUPER-speed mode, USB 3.0. This feature has not been tested yet, due to lack of hardware. This feature is useful when implementing protocols like UASP, USB attached SCSI which promises higher USB mass storage throughput. This patch also implements support for hardware processing of endpoints for increased performance. The switching to hardware processing of an endpoint is done via a callback to the USB controller driver. The stream feature is implemented like a variant of a hardware USB protocol. USB controller drivers implementing device mode needs to be updated to implement the new "xfer_stall" USB controller method and remove the "xfer" argument from the "set_stall" method. The API's toward existing USB drivers are preserved. To setup a USB transfer in stream mode, set the "stream_id" field of the USB config structure to the desired value. The maximum number of BULK streams is currently hardcoded and limited to 8 via a define in usb_freebsd.h. All USB drivers should be re-compiled after this change. LibUSB will be updated next week to support streams mode. A new IOCTL to setup BULK streams as already been implemented. The ugen device nodes currently only supports stream ID zero. The FreeBSD version has been bumped. MFC after: 2 weeks
