gianfar: Add hardware RX timestamping support
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. Signed-off-by: Manfred Rudigier <manfred.rudigier@omicron.at> Signed-off-by: David S. Miller <davem@davemloft.net>
