Subject: [PATCH] ath9k: Enable multi-channel properly
|
|
|
|
In MCC mode, currently the decision to enable
|
|
the multi-channel state machine is done
|
|
based on the association status if one of
|
|
the interfaces assigned to a context is in
|
|
station mode.
|
|
|
|
This allows the driver to switch to the other
|
|
context before the current station is able to
|
|
complete the 4-way handshake in case it is
|
|
required and this causes problems.
|
|
|
|
Instead, enable multi-channel mode when the
|
|
station moves to the authorized state. This
|
|
disallows an early switch to the other channel.
|
