Subject: [net-next v2 01/15] e1000e: Increase ULP timer
Date: Wed, 24 Feb 2016 18:14:48 -0800 [thread overview]
Message-ID: <1456366502-132841-2-git-send-email-jeffrey.t.kirsher@intel.com> (raw)

From: Raanan Avargil <raanan.avargil@intel.com>
Due to system level changes introduced in Skylake, ULP exit takes
significantly longer to occur. Therefore, driver must wait longer for.
