Subject[PATCH 3.16.y-ckt 005/126] stmmac: Correctly report PTP capabilities.
Date
3.16.7-ckt21 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Phil Reid <preid@electromag.com.au>

commit e6dbe1eb2db0d7a14991c06278dd3030c45fb825 upstream.

priv->hwts_*_en indicate if timestamping is enabled/disabled at run
time. But priv->dma_cap.time_stamp and priv->dma_cap.atime_stamp
indicates HW is support for PTPv1/PTPv2.
