| Subject: iwlwifi: mvm: clear csa countdown when AP is stopped |
| |
| From: Avraham Stern <avraham.stern@intel.com> |
| |
| commit e9cb0327b26dd7ba43a3b7a05b4b62219decf42d upstream. |
| |
| The csa_countdown flag was not cleared when the AP is stopped. |
| As a result, if the AP was stopped after csa_countdown had started, |
| all the folowing channel switch commands would fail. |
| Fix that by clearing the csa_countdown flag when the AP is stopped. |
