  *  Preliminary support for the following hardware
- *  - MikroTik RouterBOARD wAP2nD
  *  - MikroTik RouterBOARD cAP2nD
- *  - MikroTik RouterBOARD mAP2nD
  *  Furthermore, the cAP lite (cAPL2nD) appears to feature the exact same
  *  hardware as the mAP L-2nD. It is unknown if they share the same board
  *  identifier.
