Intel I210 ethernet does not work both after S3

[AceLan Kao]

Steps:
1. Only plug ethernet cable to Intel I210 Gigabit Ethernet
2. Check Intel I210 Gigabit Ethernet can be worked
3. Enter into S3
4. Resume from S3
5. Check Intel I210 Gigabit Ethernet Ethernet

Expected results: Intel I210 Gigabit Ethernet works normally

Actual results: Intel I210 Gigabit Ethernet does not work after S3

    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.

    igb: implement igb_ptp_suspend

    Make igb_ptp_stop take advantage of this new function to reduce code
    duplication.
