iavf: handle set and get timestamps ops
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.
