Subject: [PATCH] ath11k: Avoid "No VIF found" warning message
|
|
|
|
Facing below warning prints when we do wifi down in multiple VAPs scenario.
|
|
|
|
warning print:
|
|
|
|
ath11k c000000.wifi: No VIF found for vdev 2
|
|
...
|
|
ath11k c000000.wifi: No VIF found for vdev 0
|
|
|
|
In ath11k_mac_get_arvif_by_vdev_id(), we iterate all the radio to get the
|
|
arvif for the requested vdev_id through ath11k_mac_get_arvif().
|
|
ath11k_mac_get_arvif() throws a warning message if the given vdev_id is
|
|
not found in the given radio. So to avoid the warning message, add
|
|
the allocated_vdev_map cross check against the given vdev_id before using
|
|
ath11k_mac_get_arvif() to ensure that vdev_id is allocated in the
|
|
given radio.
