Subject: [PATCH 30/40] iwlwifi: mvm: CSA unbind-bind flow support for client
Date: Sun, 6 Jul 2014 12:36:06 +0300 [thread overview]
Message-ID: <1404639376-3792-30-git-send-email-egrumbach@gmail.com> (raw)
In-Reply-To: <53B917DC.5050902@gmail.com>
From: Luciano Coelho <luciano.coelho@intel.com>
Implement support for unbind-bind flow for the client roles. This
includes telling the firmware that we are not associated, removing
time-events, removing quotas and updating power management during the
actual switch, and redoing everything in the new channel.
