> The ptp_tx work is scheduled only if TSICR.TXTS bit is set, therefore
> TSYNCTXCTL.TXTT_0 bit is expected to be set when we check it igc_ptp_tx_
> work(). If it isn't, something is really off and rescheduling the ptp_tx
> work to check it later doesn't help much. This patch changes the code to
> WARN_ON_ONCE() if this situation ever happens.
