> Add handlers for the .ndo_hwtstamp_get and .ndo_hwtstamp_set ops which
> allow userspace to request timestamp enablement for the device. This support
> allows standard Linux applications to request the timestamping desired.
> 
> As with other devices that support timestamping all packets, the driver will
> upgrade any request for timestamping of a specific type of packet to
> HWTSTAMP_FILTER_ALL.
> 
> The current configuration is stored, so that it can be retrieved by calling
> .ndo_hwtstamp_get
> 
> The Tx timestamps are not implemented yet so calling set ops for Tx path will end
> with EOPNOTSUPP error code.
