controller under the same root, i.e. subsys/bluetooth/.

 The stack is split up as follows in the source tree:
 
-``net/bluetooth/``
+``subsys/bluetooth/``
   The core stack itself. This is where the HCI command & event handling
   as well as connection tracking happens. The implementation of the
   core protocols such as L2CAP, ATT & SMP is also here.
