From 51892dbbd511911c0f965a36b431fc3e8f1e4f8a Mon Sep 17 00:00:00 2001 From: Stanislaw Gruszka <sgruszka@redhat.com> Date: Mon, 6 Jun 2011 15:11:30 +0200 Subject: [PATCH] iwl4965: set tx power after rxon_assoc 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.
