. This is considered
safe because users wanting HW timestamps must initialize the eTSEC clock
first anyway, e.g. with the recently submitted PTP clock driver.

this patch series adds support for hardware time stamping to gianfar. It uses
the new SO_TIMESTAMPING infrastructure to deliver raw hardware timestamps to
user space applications.
Freescale CPUs with an eTSEC are able to time stamp all incoming network
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.

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.

This ioctl command is required for enabling hardware time stamping support
for network packets, see Documentation/networking/timestamping.txt. At the
moment nothing will be done for all requests that enable time stamping and
thus ERANGE will be returned.

in the SIOCSHWTSTAMP ioctl command to determine if HW time stamping
support is available.

This patch configures the eTSEC to insert time stamps into all received
packets as padding alignment bytes. During the clean_rx_ring operation
these raw time stamps are extracted and copied into the
skb_shared_hwtstamps struct of the skb if required.
