| 8 | commit e9cb0327b26dd7ba43a3b7a05b4b62219decf42d upstream. | |
| 9 | ||
| 10 | The csa_countdown flag was not cleared when the AP is stopped. | |
| 11 | As a result, if the AP was stopped after csa_countdown had started, | |
| 12 | all the folowing channel switch commands would fail. | |
| 13 | Fix that by clearing the csa_countdown flag when the AP is stopped. | |
