Subject: [PATCH 08/10] iwlwifi: mvm: Add preemptive flag to scheulded scan
Date: Sun, 12 Jul 2015 20:08:18 +0300 [thread overview]
Message-ID: <1436720900-18588-8-git-send-email-emmanuel.grumbach@intel.com> (raw)
In-Reply-To: <1436720814.17999.2.camel@intel.com>
From: Avraham Stern <avraham.stern@intel.com>
Add preemptive flag to scheduled scan command flags. Without this
flag, all scan requests after scheduled scan was started will be
delayed until scheduled scan stops. As a result, P2P_FIND will be
blocked while scheduled scan is active.
This flag was omitted during refactoring.
