Message-Id: <1467235982-55437-12-git-send-email-jeffrey.t.kirsher@intel.com> Date: Wed, 29 Jun 2016 14:32:58 -0700 From: Jeff Kirsher <jeffrey.t.kirsher@...el.com> To: davem@...emloft.net Cc: Jacob Keller <jacob.e.keller@...el.com>, netdev@...r.kernel.org, nhorman@...hat.com, sassmann@...hat.com, jogreene@...hat.com, Jeff Kirsher <jeffrey.t.kirsher@...el.com> Subject: [net-next 11/15] igb: call igb_ptp_suspend during suspend/resume cycle From: Jacob Keller <jacob.e.keller@...el.com> Properly stop the extra workqueue items and ensure that we resume cleanly. This is better than using igb_ptp_init and igb_ptp_stop since these functions destroy the PHC device, which will cause other problems if we do so. Since igb_ptp_reset now re-schedules the work-queue item we don't need an equivalent igb_ptp_resume in the resume workflow.
