Subject: qcacld-2.0: Trim operation classes to max supported in change station
|
|
|
|
Operation classes supported can be controlled by user, which can
|
|
be sent greater than the max supported operations. This results
|
|
in stack overflow in change station command.
|
|
|
|
Add check to validate operations supported param given by user
|
|
and if it exceeds max supported value, set it to max supported
|
|
value.
