From 8646f7b4cdf2d0557e718c4524a3e31455b92ad7 Mon Sep 17 00:00:00 2001 From: Jacob Keller Date: Tue, 24 May 2016 13:56:31 -0700 Subject: [PATCH] igb: call igb_ptp_suspend during suspend/resume cycle 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.
