  |  Bit | Band GHz | Value | Description          | Default |
  |------+----------+-------+----------------------+---------|
  |    0 | 2.4GHz   |     0 | Controlled by NIC    |       0 |
  |      |          |     1 | Force disable 2.4GHz |         |
  |    1 | 5.2GHz   |     0 | Controlled by NIC    |       0 |
  |      |          |     1 | Force disable 5.2GHz |         |
  |    2 | 5.8GHz   |     0 | Controlled by NIC    |       0 |
  |      |          |     1 | Force disable 5.8GHz |         |
  |    3 | 6.2GHz   |     0 | Controlled by NIC    |       0 |
  |      |          |     1 | Force disable 6.2GHz |         |
  | 31:4 | Reserved |       | NA                   |       0 |

The implementation follows document 559910 Intel Connectivity
Platforms BIOS Guideline revision 9.2 specification.
