| * This function issues commands to initialize firmware. |
| * |
| * This is called after firmware download to bring the card to |
| * working state. |
| * |
| * The following commands are issued sequentially - |
| * - Function init (for first interface only) |
| * - Read MAC address (for first interface only) |
| * - Reconfigure Tx buffer size (for first interface only) |
| * - Enable auto deep sleep (for first interface only) |
| * - Get Tx rate |
| * - Get Tx power |
| * - Set IBSS coalescing status |
| * - Set AMSDU aggregation control |
| * - Set 11d control |
| * - Set MAC control (this must be the last command to initialize firmware) |
