Subject: iwl4965: set tx power after rxon_assoc
From: Stanislaw Gruszka <[email protected]>
commit 51892dbbd511911c0f965a36b431fc3e8f1e4f8a upstream.
Setting tx power can be deferred during scan or changing channel.
If after that correct tx power settings will not be sent to device,
we can observe transmission problems and timeouts. Force to send
tx power settings also after partial rxon change, to assure device
always be configured with up-to-date settings.
