Subject: [PATCH 01/12] iwlwifi: mvm: enable scheduled scan on newest firmware
Date: Mon,  8 Sep 2014 19:56:06 +0300	[thread overview]
Message-ID: <1410195377-10075-1-git-send-email-egrumbach@gmail.com> (raw)
In-Reply-To: <540DDF37.5030801@gmail.com>

From: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

Scheduled scan was disabled because of a bug in the firmware.
The firmware reported support for this feature, but enabling
it led to assertions.
The bugs have been fixes in latest firmware versions, so that
we can re-enable the feature on latest firmwares only.
