I think it might be, or at least something similar to this.
I think that can be fixed with the link check you added. I think we
actually have a copy of the current link status in the ice_ptp or
ice_ptp_tx structure which could be used instead of having to check back
to the other structure.
I'm just hoping not to re-introduce bugs related to the hardware
interrupt counter that we had which results in preventing all future
timestamp interrupts.
