Browse Source 
Implemented function level reset.

Implementation is:
Make sure we are root (otherwise, return insufficient permissions)
Make sure no one has the device open
    (otherwise, return hande object in use)
Close our file handle
Unbind the device from the kernel driver
Make sure no one still has the device open
    (otherwise, kill them)
Perform function level reset (FLR)
Rebind the device to the kernel driver
