gianfar: Add hardware TX timestamping support
If a packet has the skb_shared_tx->hardware flag set the device is instructed to generate a TX timestamp and write it back to memory after the frame is transmitted. During the clean_tx_ring operation the timestamp will be extracted and copied into the skb_shared_hwtstamps struct of the skb. TX timestamping is enabled by setting the tx_type to something else than HWTSTAMP_TX_OFF with the SIOCSHWTSTAMP ioctl command. It is only supported by eTSEC devices.
