| This driver adds support for using the ENETC 1588 timer |
| as a PTP clock. This clock is only useful if your PTP |

| packets using the SO_TIMESTAMPING API. |

| help |
| Enable hardware timestamping support on the Ethernet packets |
| using the SO_TIMESTAMPING API. Because the RX BD ring dynamic |
| allocation has not been supported and it is too expensive to use |
| extended RX BDs if timestamping is not used, this option enables |
| extended RX BDs in order to support hardware timestamping. |
