USB 3.0 Hub Changes
Update the USB core to deal with USB 3.0 hubs. These hubs have a slightly
different hub descriptor than USB 2.0 hubs, with a fixed (rather than
variable length) size. Change the USB core's hub descriptor to have a
union for the last fields that differ. Change the host controller drivers
that access those last fields (DeviceRemovable and PortPowerCtrlMask) to
use the union.
Translate the new version of the hub port status field into the old
version that khubd understands. (Note: we need to fix it to translate the
roothub's port status once we stop converting it to USB 2.0 hub status
internally.)
Add new code to handle link state change status. Send out new control
messages that are needed for USB 3.0 hubs, like Set Hub Depth.
This patch is a modified version of the original patch submitted by John
Youn. It's updated to reflect the removal of the "bitmap" #define, and
change the hub descriptor accesses of a couple new host controller
drivers.
