Subject: [PATCH 14/38] iwlwifi: mvm: add debugfs file for misbehaving U-APSD AP
Date: Thu, 22 Jan 2015 22:33:05 +0200 [thread overview]
Message-ID: <1421958809-3371-14-git-send-email-emmanuel.grumbach@intel.com> (raw)
In-Reply-To: <1421958313.6424.2.camel@egrumbacBox>
From: Johannes Berg <johannes.berg@intel.com>
As this functionality relies on getting a firmware notification
it is difficult to test. Allow accessing the data for it from
debugfs to be able to trigger all kinds of scenarios to test.
