Given this architecture, this driver cannot be used unless there is a
switch driver as well. This driver is nearly ready to be merged. So
what are your plans for the switch driver? Do you have a first version
you can post? That will reassure us you do plan to release a switch
driver, and not use a SDK in userspace.
