[PATCH 4/8] iwlwifi: mvm: clear csa countdown when AP is stopped

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Avraham Stern <avraham.stern@xxxxxxxxx>

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.
