Matthew Vick 1f6e8178d6 igb: Prevent dropped Tx timestamps via work items and interrupts.
In rare circumstances, it's possible a descriptor writeback will occur
before a timestamped Tx packet will go out on the wire, leading to the
driver believing the hardware failed to timestamp the packet. Schedule a
work item for 82576 and use the available time sync interrupt registers
on 82580 and above to account for this.
