> The device is configured to insert hardware timestamps into all
> received packets. The RX timestamps are extracted from the padding
> alingment bytes during the clean_rx_ring operation and copied into the
> skb_shared_hwtstamps struct of the skb. This extraction only happens if
> the rx_filter was set to something else than HWTSTAMP_FILTER_NONE with
> the SIOCSHWTSTAMP ioctl command.
> Hardware timestamping is only supported for eTSEC devices. To indicate
> device support the new FSL_GIANFAR_DEV_HAS_TIMER flag was introduced.
